Land:

The deck has a pretty standard manabase.  I probably need to fit in a basic forest actually, because with all the RG theres magus of the moon floating around and he's a pain without a mox.

The only thing to note is the tolarian academy.  I still don't like it, but I can't really see library being played over it either, because there have been a few games that the U mana has pushed me over the top.  Not sure what to do with it yet, just like everybody.

Creatures:

No plats or other creatures because once tyrant hits, there isn't going to be much my opponent can do other than REB him.  Hopefully I will be bouncing their permanants or cunning wish up brain freeze ftw.

I'd like to fit trike as he does good things such as pick off smaller creatures and he is very castable from my hand, but if I'm oathing and I hit him first, I'm not going to be too excited.  The only other creature I would consider would probably be eternal witness but I took it out originally because it seemed like win-more.

Artifacts:

Something that I wanted to change about the deck is this, NO SOL RING.  I know its not that huge, but I can't justify the card.  What it offers (T2 intuition/wish/additional artifact for academy/tinker) is not worth a slot in the MD to me.  It doesn't help me with any 2 mana T1 plays which is what the deck really wants.  I'd rather have a tutor which is going to make for a better topdeck and better earlier draw to search up oath.

The rest of the artifacts are standard.  Again, max out your T1 2 mana plays.

Tutors:

Things to note right now is that imperial seal seems kind of random.  It does its job, but I can't help but wonder if theres something better to replace it with (maybe ponder which isn't technically a tutor).  Intuition has been quite a star as it usually fetches up 3 oaths ftw.  Merchant scroll is really the most odd one in a list without gush or any gifts.  Scroll has been extremely good to me, though.  Obviously ancestrall is a good target.  Intuition/cunning wish are runners up (fetching up cunning wish in particular when I have tyrant on the table is useful to win on the spot).  Even fetching up brainstorm to shuffle away tyrant.  The point is, I really noticed a difference in the power of the deck after merchant scroll was added.  I don't know that I would be playing mystical if it was not for merchant scroll even.  Mystical normally will end up grabbing ancestrall or yawg will.  Crop rotation is in the side to cunning wish for if I need to get orchard right away.

Disruption/protection:

The whole 4 force, 2 drains, 1 MisD, 4 duress has become pretty standard these days, so I didn't really mess with that too much yet.

SB:

Definately needs work. 

SB: 1  Misdirection - I have yet to wish for it.  Seems way too situational although if I ever need FoW #2 in hand it might be useful.
SB: 1  Brain Freeze - win condition obv
SB: 1  Rebuild - stax (do I really need this?)
SB: 1  Echoing Truth - empty the warrens and meddling mage
SB: 2  Trickbind - vs. combo
SB: 1  Tinker - grab plat to make trouble for certain decks
SB: 1  Research/Development - fight extirpate
SB: 1  Platinum Angel - just plain beats certain decks
SB: 4  Leyline of the Void - ichorid/flash
SB: 1  Sundering Titan - not entirely sure why this is here
SB: 1  Crop Rotation - purely to wish for to get orchard

I doubt people are really going to discuss my list that much, but this deck is going to house in this creature heavier (than previous vintage) format.

I am for thoughtseize all the way, especially because of the recently R/G deck that has shown up.  And nabbing magus of the moon has helped me win a game as well.  In my opinion, against an unknown opponent there is no reason NOT to run it (unless the deck you're playing with doesn't care about creatures eg. oath).  Being misdirected sucks its true, but most decks that even run blue have only 1 MisD anyway.  It happens, but not that often.  The two life points can matter, and in fact they have for me, but I managed to strip a dryad that would have cost me more than 2 life if it had been played.  I just can't see not running it with the current metagame having more and more creatures.

I think that sapphire medallion could be a much stronger option than helm of awakening.  Back when scourge had come out and the banned/restricted list wasn't updated yet, there was a desire deck that ran sapphire medallion, cloud of fairies, frantic searches and 'tap for 2' lands.  Needless to say, you hit 3 lands and won with sapphire medallion in play.

I think that Bob is more than likely too slow.  Granted I love the card, but I feel its kind of similar to my distaste for Necro in the deck.  You don't replace him with a card until next turn.  If the game lasts ANOTHER turn then he did his job and netted you a card for some amount of life and 1B, but for the same cost you could have just played night's whisper and probably lose the same amount of life.  His 2/1 body doesn't really do much as far as a clock either.  9-10 turns isn't so great.

Still, by all means, test him out.  He's working wonders in other decks in every format.  I'm just saying that you need to make sure that the game will last 2 more turns for him to be any better than night's whisper.

I too would not cut bargain.  In the type 1 tournament in NJ I just played in, I resolved bargain turn 2 twice with counter backup!  Needless to say, I simply won after that.  There has also been several casual games that I've played where Bargain is a much easier win around a card like leyline of the void.
