Unfortunate the poll has ended.
Still, I'm 17 right now, picked up vintage this winter. It's quite interesting to see that would make me the younger here. I feel like younger players tend to go for casual decks or type two, so I'm playing with guys around 20-22 to playtest vintage/legacy.

I played against Serge Metz if I remember right, twice at BoM.
I didn't feel this deck was powerful. Or he didn't really had good games. I played belcher at the time, but I've always won on goblins at like, turn 7. IMO, it lacks a good clock, otherwise it's quite interesting.

For what I know, this list seems very good. Played against it at two tournaments. Both times it kicked my ass. Not because I was unlucky, but it had a very good clock, and enough spheres. Most of the decks can't deal with both at once.

Well, a friend of mine made 6-2-1 with Oath, so not that bad. And I must admit he did a lot of missplays. However I didn't see much oath players in the tournament, that might explain.
Unfortunately nothing interesting on my side, 2-3 and 3-3, with ANT and Belcher, had a lot of fun, but lost to bad estimations with ANT.
Can't wait till next year!

I see it played with Iona pretty easily.
Iona naming blue and you having a counterspell is very strong, because if they're trying to get rid of Iona, you could just get away with your counter. Emrakul is bigger than Iona, but unfortunately doesn't protects himself as good as Iona, by stopping opponent's counterspells or threats. In a deck with two targets, he's still the good complement to Iona, mostly because he's 15/15 and is better protected than Hellkite Overlord or others.
Big Plus, it's the Prerelease card, which will make it cheap. Don't want to waste another fourty bucks like on another Jace-like card. But that's certainly not the point here.

Me and my friend made respectivly 12th and 10th in this tournament with Tezz. We were both running Hurkyl's recall but only one. I actually won against Stax and did not do pretty bad against MUD, my missplays costed me the game and must admit that an okay hand (like with plenty of mana, Dark Confidant and/or 2 counters) + any way to tinker makes your game, if you play Sphinx, of course.
I learned that Sphinx just makes your opponent scoop when it's on the table, and regretted I had the Leviathan. Otherwise one Hurkyl's recall is sufficiant, and I think I might run Imperial Seal + Jace 2.0 that help a lot in this matchup. Imp Seal tutoring the Tinker, Jace bouncing Golems and letting you countering them or Thoughtseize them.
If you don't have any of these in your hand, being able to hardcast counters like FoW and Drain through 1-2 Spheres is also good against this deck (If you have a hand with moxens, lands and 2 Counters). Since you'll have enough counters and hand disruption to get rid of their threats, you can wait for a tutor or a win condition to come for a reasonable amount of time.
Also, post sideboard, you've got a nice game plan if you play Nature's Claim and Sower of Temptation, which are both really useful against MUD. What you're trying to do is to let them put 1-2 spheres and get as much mana sources as possible on your side in your opening hand. Then you cast Hurkyl's recall and counter / destroy whatever you want and repeat that 1-2 times so they won't have any hand, but you'll have some resources as you probably had a Dark Confidant. Then sower just leaves you with a good blocker or an excellent threat. MUD often collapses when it comes to be forced to topdeck, so you're trying to buy time to get to that point.

You still have a lot of MUD, but also a lot of other decks, H-calls are not very efficient in multiples otherwise. They belong to the sideboard.
Also MUD can't deal with an early game Tezz, so I'd leave him in.
My 2c

I also agree on this. Turn 2 Drain enables Turn 3 Tezzeret or Dark Confidant + Top + UU Open for anything, or anyhing else you might think about. It's good with any spell that requires uncoloured mana in the early game, because it enables you to play more spells quickly. Even if it's only two uncoloured mana, it changes your plays.

Double post. Sorry.

Usually when playing Tezzeret I find myself countering more creatures than non-creatures spell against MUD and fish. 1 sphere is just fine to go through, 2 becomes quite difficult, 3 really annoying, but what about creatures? None of these is smaller than a 4/4 (Excepted Metalworker) and Fish has Tarmogoyf or Qasali Pridemage, that makes a lot of potential good threats. Can spell pierce counter them? Certainly not. Having a turn 2 Mana Drain setup is always better than having 4 Spell Pierce in your deck. Turn 1 doesn't see that much broken plays. Now we spoke about the beginning of the game, I'll set aside endgame situations, where Spell Pierce is a card to cycle and becomes worst than any other card.
This is why Spell Pierce is so Bad.

Well, seems like green is a good option.
Here's what the changes I did to the 55-cards list on the beginning of this topic:
-1 Fire / Ice
-3 Volcanic Island
-1 Rebuild
-1 Tezzeret
+1 Hurkyl's Recall
+1 Library of Alexandria
+2 Tropical Island
+1 Darkblast
+1 Dark Confidant
+1 Tendrils of Agony
+2 Sower of Temptation
+1 Regrowth

So, I played a list not so different from that in a 45-man vintage event and it went pretty well, the above version is my revised one after the tournament.
I've been really impressed by Tendrils of Agony. Our win conditions once Time Vault is gone are not always good. Tendrils can help kill an opponent that's not careful enough or that removed our Time Vault win condition. Sower of temptation seems very good against fish and MUD, and always steals Dark Confidant. This card bends the game whenever it's played, exepted against Combo decks.
Regrowth is completely awesome, it's basically a "joker", whenever you need anything back again, just like a Sower, a Recall or anything from your gifts package, it's always helpful. It helps a lot to deal with anything post-SB, taking back your sideboard cards you need to be very efficient against a specific deck (Leyline of the Void, Massacre, or whatever) Also, I've never been decieved with Library of Alexandria, excepted when on the play against MUD, otherwise if you activate it quickly, it will help you defeat everything but a Wasteland or a broken play from your opponent.

Also, with green, my sideboard has become:
4 Leyline of the Void
1 Nemesis Trap (I just like it but actually never had it in hand yet, it just seems to be excellent against oath and fish.)
1 Massacre
3 Nature's Claim
1 Pithing Needle
1 Hurkyl's Recall
+4 Free slots (Here I'd appreciate a lot your input, about what I should side-out and side-in for certain matchups).

I've never been disappointed with Massacre, Rebuild, Hurkyl's Recall or Nature's Claim, the only two "test cards" in there are Tarmogoyf and Nemesis Trap, which I found to be very useful for MUD and Fish Matchups, and as the Tarmogoyfs also provide a quick clock against Tezz decks, it might be used in this situation, but I'm not sure if there's anything to take out from the Maindeck.

Here's how my SB plan looks like:
MUD:
-1 Duress
-1 Darkblast
-1 Tendrils of Agony
-1 Tezzeret
+3 Nature's Claim
+1 Hurkyl's Recall

Fish:
-1 Tezzeret
-1 Duress
+1 Massacre
+1 Nemesis Trap

Mirror:
-1 Sower of Temptation
+1 Nature's Claim

Oath:
-2 Sower of Temptation
+1 Nature's Claim
+1 Nemesis Trap

TPS:
-2 Sower of Temptation
+1 Pithing Needle
+1 Nature's Claim

As I see, Tezzeret seems to go out against Aggro decks, and Sower against Combo / Control decks. If I wanted to optimize this I'd certainly replace these three for cards that are good in any situation, maybe 1 Jace, 1 Ponder and one other?
Maybe I'm totally off with sideboarding, but the deck seems so strong that I can't take out any of it's powerful parts.

Yay! I couldn't be there at the last one, but I'll be here this time and I'm looking forward to play my first Vintage tournament.

That's a good point, but (as certainly some others) I bought my P9 from reliable dealers, they all passed the ink pattern, black light and light test. If you're not sure your P9 is true, then you could be in trouble at anytime.

The death of proxies tournaments serves the best interest of WotC, so for sure they'll choose a solution that will make the proxy tournaments not so much interesting.

But if wizards offered to trade Unlimited P9 for like 20 of the new ones, so that players that have P9 can keep the value of these, but it would make more P9 available.
Of course that would make Unlimited P9 also a bit more rarer, which could be fixed by wizards re-releasing it slowly (Not to crash the prices) in a certain way after they stopped exchanging it for new ones. I don't have many other ideas other than simply reprinting it. I'm not very good in economy but I think that might be an alternate solution

Well, I mean, just compare Fact or Fiction to Jace. After 2 brainstorms jace has been way better than any FoF, and it's just like your fifth Dark Confidant in Tezz. But still, noone is saying that FoF is unplayable right?
I currently replaced one of the two tops by a Jace, and I'm quite happy with it.

I think you miss one point, which is that supply / demand would be important to determine the price.
If supply is high enough, power won't be expensive. But now it's up to WotC.

You're right, Alpha/Beta would surely climb a bit. But now, what about Unlimited? White border would seem ugly if it's ever reprinted in Foil or Regular black border. There's not many Unlimited collectors. Or at least not as much as for Beta
After a bit of thinking, I don't think I'd mind if they reprint anything, even if I own a lot of white bordered duals and 8 pieces of WB Power. Eternal cards, reprinted or not, will always climb once they rotated out of Type 2. And if WotC wants money, they'd better sell the duals at a high enough price (More benefits) or if they reprint them in boosters, then, make them rare enough (Just like mythics) for their value to be high enough, and not as regular rares (Which are not worth more than 10$ in the current sets).
Reprinting them as Mythic Rares, for example, would help WotC selling a lot of boosters, and not lower their value too much.
Or buy them all at current prices and then reprint them, but would WotC have enough money to invest for that?

Had I to play such a deck right now, I'd go for this:

1 Tolarian Academy
1 Library of Alexandria
6 Blue Fetches
10 Islands
8 Solomoxencrypt

4 Mana Drain
4 Force of Will
1 Ancestral Recall
1 Time Walk
1 Jace Mind Sculptor
1 Tezzeret the Seeker
1 Brainstorm
1 Fact or Fiction
1 Gifts Ungiven
4 Repeal
1 Rebuild
2 Transmute Artifact
1 Tinker
1 Sphinx of the Steel Wind
1 Thirst for Knowledge
1 Ponder
1 Merchant Scroll
1 Mystical Tutor

3 Sensei's Divining Top
3 Voltaic Key
1 Time Vault

Strong draw engines: Repeal / Top or Key / Top. Which get pretty insane quickly. Strong counters support and 2 Transmute Artifacts to find Vault whenever you need it. It draws quicker than Dark Confidant decks and doesn't care about Darkblast, too. Repeal also bounces whatever you want, so it's never useless.
I really consider getting into testing it more seriously, as I prefer Repeal over Dark Confidant.

I'll be there drafting some Revised FBB too
Prizes are awesome, and seeing some American people would be even more awesome!
Seems like few trials are not on the list, unfortunately.
Even if it's sometimes difficult to use english to get to Annecy as said above, but if you have any questions about the Swiss rail lines to get to Annecy, I might help you

Reprinting Seal would have less impact than reprinting more used cards, like Power or BoB, because it's less played.

In my opinion, Skullclamp would be better in this deck than Top. You can hit harder, and draw cards in compensation if your creature dies, it also helps with the Dredge matchup. Also I wouldn't play Null Rod but more Artifact and Enchantement hate. Like Tin Street Hooligan or Seal of Primordium.

Swords to plowshares would bend the format with Path to Exile still there, I don't think it could be for M11, and I see you couldn't help putting your favorite card in there

I definitly would play dark confidant in this deck. You will certainly loose a significant amount of life, but it often will make you win the Card Advantage battle.

I have a short question about the MUD matchup.
Is it winnable, especially with lodestone golem? I just can't imagine comboing with a sphere on the board...
I'm planning to play this deck once, but this matchup seems to be disturbing in the current metagame, as I don't see any other deck being a real threat for SCV.

It will certainly not be reprinted, not at least for a while. It's a collectible and WotC will need a long time to do this decision. If you actually need it for your decks, go for it.

I love this deck, but I hoped this articled would go more in depths in the mechanics of the deck and it's matchups. A bit disappointed, but still, quality is here.

I'd look at the ONS Foil fetches to get an idea of how promotional cards influence other cards already on the market. Before the Judge Gifts, they were a lot higher. Of course there is non-foil versions of these ones, and they didn't drop. It's difficult to predict what happens, but with limited prints such as P9, it will drop, not too low, but still. Or maybe they won't print any P9 again but some cards like Duals, which I can definitly see in a sane T2 environment.

@ Grand Inquisitor: Thanks for the input, knowing that I expect MUD, Noble Fish, Tezz and Oath to be the Decks to Beat during the 4th Bazaar of Moxen (I might be wrong, but Zendikar and WWK gave a lot to these decks, excepted Tezz).
I think I'll go like that, leaving the 55 I listed above like they are, and then, for the 5 other ones:
1 Misdirection (Good excepted for MUD).
2 Thoughtseize (Good for Everything if you land it Turn 1)
1 Hurkyl's Recall (To deal with MUD, and also Null Rod)
1 Fact or Fiction

I didn't choose to play any Echoing Truth, because what we'll usually bounce will be Qasali Pridemage, Null rod or some Spheres. Playing Hurkyl's Recall and Thoughtseize lets you deal with these guys.
Also, I think I should play LoA in the deck, since Oath and Tezz are in the format, and it can help with long term control anywhere.

Hi!
I have a few concerns about the 55-card list that seemed to be there in any tezz in the thread's poster opinion, for reference, here it is:
I don't know why there's no library of alexandria here. It's for me a strong, strong card in any matchup, even if you sometimes won't be able to cast drain, leaving a dark confidant and a LoA on the board will surely make you win if not handeled very quickly.
Also, I don't understand why you splash for Fire/Ice and only this one. For me one of this deck's strengths is to be able to fight against the mana denial from fish decks, and I'll surely change the manabase to this:

8 Solomoxcrypt
6 Blue Fetches
4 Underground Sea
2 Island
2 Snow-covered Island
1 Library of Alexandria
1 Tolarian Academy

And also, remove Fire/Ice for darkblast. Which can also kill a 2/2 creature if you cast it in your upkeep (With some card disadvantage, I must admit), and you're 100% sure to have access to it if you gift / Fact or Fiction on it.

And for the 5 other cards in the current metagame, I'd go with:
1 Fact or Fiction, I love it, and even prefer it sometimes to Gifts, since you choose what you put in your hand, even if there's not always the piece of combo you needed.
1 Misdirection, still hesitating on this one, maybe it's more for the fun that grants misdirecting Recall.
1 Repeal, lets you bounce without card disadvantage, but I'm not sure if I prefer Hurkyl's recall, knowing that we often get to bounce artifacts with Null Rod or Stax matchups. It doesn't bounce Iona, but no other card can if you consider that your opponent will name blue. For iona I'd rather search for something black.
2 Daze, I think this one helps with Noble Fish all around, especially because it plays only 3 moxens as mana artifacts and also often includes 3-4 Daze.

I'd also remove the Thoughtseize and add in another Daze, probably, I think this deck requires more free counters, feel free to discuss on this, since I'm testing for it at the moment.
