Why 2 Djinns? 1 Djinn +1 Akroma should be just as fast.

Niv-Mizzet seems also like a good Oath creature. He is a bit like Hydra or Triskelion.

The above list is not Mono White Weenie. That is just not true. You slash a color and blue is the better slashcolor for the deck.
If you look at old Extendet White Weenie lists you will see that a blue Slash for Meedling Mage is more typical for White Weenie than slashing green.

One year ago the "Meandeck Fish" would have been called WW/u. And it is WW/u. Fish decks follow the rule "Your creatures must have at least as much power as their casting cost, and they should have some ability to outtech your opponent if possible". That the rules on which WW is build.
Fish was the deck that played Standstill and tried to abuse the Standstill.

Well there is White Weenie, it just slashes Blue.

The difference is that you drop Blue in favor for green. That doesn't allow you to play the best White Weenie creature = Meddling Mage. And you lose the Brainstorm Drawengine in favor for more creatures. That leaves you with no carddraw engine.

The blue slash enabled the other deck to play Force of Will over your Seals. Force seems to be a better distruption card.

You play Whipcorder over Stormscape Apprentice. Both creatures with the same ability. Your Whipcorder cost one aditional mana and has one power more. So they serve both as good as the other.

The only gain of slashing Green instead of blue is that you can play Oxidicein your sideboard. That seems to be a bad tradeoff.

Unfortuneatly no Enchantment.

An additional Disadvantage is that Echoing Truth kills your Zombie Token.

Concerning the decklist:
Is it built for a aggro meta?
4 Swords, 24 creatures, 0 Chalice and 0 Null Rod looks wired.
It looks much more like a White Weenie Decklist with Black for better creatures and Duress. White Weenie is not necassary a bad deck, but it is no Fish.

In my opinion Time Walk is to good to be dropt. You need 2-3 Lands into play as soon as possible so you should play Walk.
Same with Lotus and the On color Mox, you need to be as fast as possible in Vintage.

Frantic Search is a card that should definatly be added to a High Tide List.

The important question is whether your decks is fast enough to survive with only 4 Force of Will for Distruption.

Since you are playing no Thirst for Knowledge I see no reason to run Top over Sylvan Libary. The Libary is way more powerful because it allows you to get ~3-4 extra cards in a matchup were life doesn't realy matters like the control matchup.

I think I would try to put 3 Null Road in the Sideboard. It is better than Root Mazes gainst Combo. Also Nul Road + Wasteland Recursion is tech. It works also exellent against Gifts.

I have switched to:
-1 Polluted Delta
+1 Cabal Pit (having a maindeck way to handle Welder or Fishes is nice)

-1 Exploration (having 2 at the same time is not good enough to play 4)
-2 Intuition
+3 Gifts

and
-1 Brainstorm
+1 Sylvan Libary (a old Keeper tradition to play a single Sylvan Libary, it is a nice card with all the shuffle effects)

Sideboard:
-2 Carpet of Flowers
+2 Nullroad (to have a better combo matchup)
-2 Forbidden Orchard
+1 Naturalize
+1 Oath of Druids (The Oath Sideboard tech doesn't need Forbidden Orchards, because I board them against aggro I can also defend myself against the Manlands of Fish with my Loam Engine)

Naturally their are some decks that want to replay a card more than once, but this deck has no other use for its graveyard.

To quote from a old Void primer:

It is generally considered a bad idea to play Brainstorm a Fish deck with Standstill.

The old Gay Fish lists couldn't use Black Lotus, because of the card disadvantage that resulted from the Lotus.

I think Oncolor Moxen and the Demonic Tutor in black decks would be better truthes

You have a theory that may be consistend, but it produces significant wrong results. If you leave the skill out your theory is consist only of some metaphysical assumptions, because skill matters. And skill is no random factor. Skill is certainly predicable, and therefore better analysable than a factor like a meteor that hits Vroman.
That meteor would be a random factor, but skill is not. By the way if a player can't concentrate that is a lack of skill.

If I try to get matchup data I propose a thought experiment.
I give 2 team meandeck players a Gifts built and Stax built. They switch the decks after each match. They play 100 matches. Then I would gain a knowledge of the matchup.

On the other hand I take the the same decks to a local shop in which I meet two players who know the magic rules but have never before played T1 in their lives.
They shall also switch the decks after each match and they play also 100 matches.

I would think that the two players in the local shop get a drastically different matchup than the two meandeck players.

Logically you don't know whether it is true or false.
"There are no ghost and therefore all ghost are bodybuilders is true" but “All ghosts are bodybuilders.  There are no ghosts.â€? can be true as well as false because you can conclude a right statement from a false statement.

Is that a honest question? Will is a bomb. Even when the Void is in play a Will can still Recycle a Wasteland.

  If you plan to play Void on turn 3-5 in a deck withoud carddraw and you aren't playing 4 Voids than there is something wrong with your gameplan.
If you Netdeck a deck like Nether Void you should at least understand it's gameplan. The deck tries to distrupt the enemy in the first turns and uses Void only to prevent the opponent from recovering.

I would rather play Crucible/Chimeric Idol/Nether Spirit than your creature base.

Even if all players are identical skill is still important. If everyone know how to play Gifts and nobody knows how to play Grim Long, Gifts will win with a higher percentage than if nobody knows how to play Gifts and everyone knows how to play Grim Long.

That is only true if there is only one future. If Schroedingers cat is only alive or dead when someone opens the box, their could also be multiple futures from the start point of a tournement. And random shuffling is based on some electrons that move in our brain so chaos theory should have an effect in there.
So you have to look in who many futures the cat lives and in who many it dies.
You have also to look in who many futures which deck wins.
So you have to remove all random factors and replace them by Fuzzy logic: A coin flip is 50% tails and 50% heads instead of a coin flip can be 100% heads or 100% tails.

Where do you want to take your mana to play counterspells from?
You need to tap out for your Tap 3 Lands/Draw a Card combo.
You lack the manasources to do something with your cards. You need Fastbond and or Exploration to gain the full advantage of Life from the Loam.
That allows you to trade cards you draw into tempo by dropping a Wasteland for free in addition to your other plays each turn.

I can make a better prediction which list has the greatest possibility of winning the tournament when I have the same of the player on the decklists.

And the metagame, the decks that are played by other people are depenedent on the deck itself?
They are external factor that are independent of your decklist. They are the same category as things like your gameplans for your matchups.

My statement is that it could be deck C for Player B and deck D for player A.
This is not about incomplete knowledge. If we only look at the decklist, we have to assume that the other factors that determine who wins the game are fixed.
Even when we do not know the factors, they are those factors. A chess player can't calculate all variants, but he can assume that there are all variants that results from the game rules. Their is nobody who throw a ball on the board when the player does a certain move.
There are variants that have a higher win chance and those that have a lesser win chance.
He tries to find one of the higher win chance variants.
But he has to assume that the rest of the game is theorethicly predictable for making good moves.

If you assume that there is a specific result of a decision you can't drop the factor of the player just because you want to.
To quote Sun Zi: If you know the enemy (the metagame) and know yourself (you, the player) , you need not fear the result of a hundred battles. 

The decisions that are made by a player are a huge factor which determines how good a deck performs.
From the perspective of having to make the choice which deck to play at a given moment having perfect knowledge would mean knowing the metagame and yourself and how the two interact with a given deck.

Their is a mayor difference between insufficent playskill and plain dumb luck. Insufficent playskill partly predictable. All theoreticly predictable data has to be taken into account to get a objective result.

I am not saying that making tactical (those that depend on a specific situation) mistakes is predicable and a lot of mistakes come from general strategic misunderstanding of the perfect game plan of a deck.
If someone realy likes to play his deck as fast as possible, he just follows blindly the concept of getting your opponent to 0 life as fast as possible, he is better of with playing Belcher than playing a slow control deck and not using the strategic control ressources of the control deck.

Conclusion: The gameplan of a deck is just as important as the cards in the deck. It can't be left out when it gets to chosing the best decklist.

The question is is the best deck for Player A the same as for Player B? If it is not it is only a subjective term.

Player A may have enough strategic understanding of the decks in question to have a 60% win chance with deck C and a 65% win chance with Deck D.
Player B may have enough strategic understanding of the decks in question to have a 65% win chance with deck C and a 60% win chance with Deck D.

The point is that game theory says that their is a best strategy in a given field. But strategy is more than just the deckchoice.

You if you have 10 manasources (note that they need to be permanent sources and no Lotus Mana) you have the LotL engine going or a Crucible in play. And then you can destroy the manabase of your opponent. So while I am "stalling out" I destroy 2 lands per turn.

But even when it is a situation in which they have force+drain in hand and a living manabase this is no situation in which the Echoing Truth combo is realy useable.

You don't draw that many cards that you have a full set of moxen in play, mana is mostly produced by lands in this deck.

Having basic Lands is good against decks like Stax or fish.
And I would only need more black sources if I would play Pernicious Deed. It would probably weaken my stax Matchup and only improve the aggro matchups. I have not much problems against Aggro because of the Oath Sideboard plan, the Staxs matchup seems more important to me at the moment.
But I should probably test the Deed.

Yeah, but Echoing Truth doesn't destroy the Oath.

Playing threats is IMO better than playing anwsers. Thats why Gifts is better than Keeper.

I win Game one mostly with the infinite turns combo. But when the opponent boards enough graveyard hate I switch to the collosus plan.

But after the first Tinker the second is probably powered by a Yawamoth Win anyway. And the Will produces a situation in which a Echoing Truth wouldn't realy help and a turn more or less would be insignificant because the Gifts player has a good counter wall.

Blocking Shamans with Winess sound like a good plan. I know that bouncing a Darksteel Collosus is no win, but it brings me back into the game.

I am at the moment fine with 2 Intuitions and 3 Gifts. But that results in a 61 card deck

Yes, that is true.
But taking 11 damage from a collosus is okay. Decks who play Tinker-Collosus usually don't play beats to do the other 9 damage. I have still a few lifepoints to do a bit FoWing or Fetching, so what is the problem? Yes, Echoing Truth is a better bouncer and yes Mark is a bad card for bouncing opposing creatures and the Echoing Truth-Infinite Turn combo is realy bad. The Mark infinite turn combo is good. 

The mindslaver position is different because you can destroy your opponents hand in addition to taking turns. And for a matter of fact th infinite mindslaver combo needs a lot more set up.

But think about the Oath Matchup, they play the Oath and you have around 2 turns left. If you resolve the infinite turns combo you win. This is a typical situation in which you need to win now. And gathering 4 additional mana sources needs maybe 2 additional turns.
Sure you can try to counter Oath by bouncing Oaths creatures a little, but this doesen't gives you a win and it leaves the threat in play.

If I have already 10  manasources out I have probably already won the game. In this deck having ten mana sources out often means your opponent has ~ 0 lands in play. If I have that mana mana I can also hardcast Darksteel Collosus but that doesn't make Tinker 'unneeded'. And Tinker realy can't do much else than getting Collosus, so discard it?

Have you considered Unearth? It works realy great with your Witness and your large graveyard.

I would rather take out Vampiric than cutting Demonic Tutor.

So your argument is:
"Because a 10 Mana Combo which requires 4 cards doesn't work (or is unnecassary) a 6 Mana combo which requires only 3 cards will not work"?
And if I have the 4 extra mana and an extra witness the combo is even more difficult to distrupt than the Echoing Truth combo.

In this deck the "Land war" is about card advantage. When LotL give me 3 useable (this word is the problem of LotL, it needs Exploration to be solved) cards for only 2 mana, I can outplay Gifts or Staxs.
Crop Rotation results in permanent disadvantage. I rather take a Intution to tutor my Strip Mine because Intution gives me LotL and a Wasteland or a Cycleland on top. And here I am not sure that Gifts can replace all Intuition, because it comes one turn later.

Pernicious Deed could be a replace for Seeds of Innocence as mana artifact destroyer but I think that I have not enough black manasources for Deed. Tutoring Deed and playing it in the same turn requires 2 black Mana and Mystical Tutor can't even search Pernicious Deed.

Seeds are also used in other matchups as tool against mana artifacts when enough damage is already done via Strip Mine Recursion.
Life of the Loam/Exploration is a good engine against Stax.

You are probaly right that Gifts is very powerful. I will test a split of Intutions/Gifts.

If a Exploration lays already I am confident that Life from the Loam+2 Lands is clearly better. If not it is as strong as Accumulated Knowledge. Keep also in mind that you tutor for power cards when the LftL wouldn't work in the situation.
Exploration could be played before the Chalice comes into play.
On top of that you can switch to the Tinker plan. And one Strip Mine per turn can also sometime be enough to distrupt a opponent enough, remember the Stax player is also hosed by  his Sphere of Resistances.

If I resolve a Intuition I have a Strip Mine for the basics.

I am looking forward to reading a 'Sex' list with Mark of Eviction. It would be interesting if it affects other card choice in your deck and how often you win with beating your opponent with Werebears afterwards.

In my counting it would be the fourth chance of winning. Infinite Turns, Lock your opponent and 'Tinker Collosus' are already three ways.

Quoting from a article from Stephen Menendian about Gifts:
[/url]
Mana Drain is not so important when you aren't playing pure control.

Imagine a Draw like: Exploration/Wasteland/Tropical Island/Fetchland/Life of the Loam/xxx/xxx, your opponent starts with playing a Nonbasic Land.
You play Tropical Island/Exploration/Wasteland/Destroy Land go.
Next turn you play Fetch search a Land then play Life of the Loam for a Fetch/Wasteland. Maybe your opponent sees now his problem and forces the Life of the Loam. Well you get a new one next turn.
Conclusion Exploration is an effective Lock Card. It is no bad card. It is a broken card. In this Example the opponent probably had to force it to be in the game. And that isn't bad for a 1 mana casting cost card.

If you tutor with Intuition your Strip Mine your opponent can also not go back to the Basicland defense. When you have 2 Strip effect per turn leaving a Fetchland open also doesn't allow the opponent to come back.

I play a Lock/Combo Route. If I wanted to play aggro combo I would rather play Werebears than Vinelasher Kudzu's. In fact this deck envolved out of a aggro-combo list ('Sex'), but I think aggro combo isn't realy good. It gives your opponent to much time. If I attack the Mana base it has an immediate effect. And if I get him to 0 Lands it is also nearly a win.

Sex does play four counters. I have more distruption than sex.
Life of the Loam is not so much a searcher, it is distruption. Life of the Loan/Crucible and Exploration is just as good in term of manaproduction as Werebear and Birds in 'Sex'. A Werebear or a Vinelasher Kudzu needs a few turn to put pressure on the opponent. Life of the Loam can also put pressure on them and it has an immident effect.

The problem is that you need to tap out to use Life from the Loam to it's fullest potential. For that reason it has a lot of disharmony with Mana Drain. Much like Bazaar of Badgad + Manadrain. And Life from the Loam works so much faster with Exploration.

My game plan is to play the card the second turn. Gifts come a turn later.

At the moment my testing ground is MWS. I know that many people who play their aren't playing good. But it works good against the good decks that show up.

The combo costs 10 Mana with Crystal Shard. 6 Mana is better than 10 I think. You can also pitch it to force and switch to the plan of Gifts Collosus/TimeWalk plan. (and this deck is good at Time Walk recurssion). I don't rely on one creature. Beating with a Witness does also work when you have infinite turns. If you destroy the whole board of your enemy with Strip Mine recurssion and Seeds of Innocence you can even beat your opponent with one Witness without Time Walks.

The main Win-Combo:
Eternal Witness + Time Walk + Mark of Eviction
is a 6 mana win.
Tinker Colossus serves as an alternate Win.

What to intuition for is one of the key questions of the deck.
You have to basic plans:
A power set up: Ancestral Recall/Timewalk/Tinker. You play this when you have Eternal Witnesses/Regrowth/Dreams in your hand.
The other Distruption setup is either:
Life from the Loam/Tranquil Thicket/Strip Mine is  good  when you have no Exploration or Fastbond or when you have one get someting else in place of the Cycleland.
The Cycleland is neccsary when you have only one land per turn to have not to much unused cards in your hand.

One black mana producing land is thanks to Life from the Loam enough for the two card slash.

Note the synergy between Life from the Loam and Brainstorm. You can either put lands back to your library or put the cards on top of your library into your graveyard via dredge.
Discarding the lands for Nostalgic Dreams is a similar card quality accelerator.

The 2 Life/1 Crucible is a good split because multiple Lifes are bad. Life has the advantage over Crucible in the early game because it is "counterresistent" and tutorable via Intuition.

Mark of Eviction can also be used as second class bounce against the creatures of your opponent.

Seeds of Innocence is a good silver bullet against Stax and a way to destroy mana artifacts.

Gush is in question, but it seems to be to good  to be left out in a deck with 4 Exploration. Maybe Gift of Ungiven would be better in this slot.

0 Mana Crypt:
You want to win with infinite turns, Mana Crypt produces problems.
0 Mana Drain:
You have a lot of sorcery speed cards and need to tap out.
0 Birds of Paradise/Werebears:
Exploration is just better in this deck.

Ashnod's Altar is in my opinion better than Krark-Clan Ironworks. 4 Mana is a lot, and the altar does often about the same as Ironworks.

Is there a reason for the lack of Junk Diver's?

I think you should play Karplusan Forest over the fechies. You have already enough forests for kirds.
Fetchies + Rootmaze =

Over a game in which you see maybe 30 cards. Your chances to see specific card are ~ 1/31 more worse than in an 60 card deck.
If you want to see 5 cards at much as possible(Recall/Timewalk/Black Lotus/Yawamoth Win/Your Silverbullet Xy), and play 7 rounds in a tourment you will see 5*7*1/31= ~1 important card less than a player how plays a 60 card deck.

It is irrelevant to look at a per draw chance to draw a specific card, you have to see the hole picture over a larger time.

I have played W/U sometime ago. I found Weathered Wayfarer to be a realy good creature. The Abillity to tutor up Wastelands if your opponent drops more lands than you is realy good against all kinds of control.
Playing fewer lands would  also work well with Aether Vial i think.
It can also Tutor more Mishras against decks like madness.
It is also good after SB when you bring Maze of Ith in.

How about a single Battlefield Scrounger?
If you have Oathed two times you put Anything - Ancestral Recall Time  Walk on top of your library.
You walk and can put replay Time Walk and playing your whole deck.
Or you can go Yawamoth Will up a combo. (Then you could use Krosan Reclamation in the case your Scrounger get sworded to combo kill too Crucible/Fastbone/Orb)

Two Yosei, the Morning Star would be also possible if you want to play blessing.
