your mask deck is pretty sweet. although many people have done mask decks similar in the past, none had quite the innovative edges you put to it nor looked like yours. It really looked like you just found strong synergies with 'naught and ss. 'naught + Stifle is pretty good.
I guess, you didn't even try the link, I provided, right?

For the record: This is the deck I played weeks before. I won a tournament with it and made it public right here:
4 Force of Will
4 Brainstorm
4 Stifle
2 Mana Leak
2 Merchant Scroll
1 Daze
1 Ancestral Recall
1 Time Walk
1 Echoing Truth
1 Psionic Blast
4 Dark Confidant
3 Duress
1 Demonic Tutor
1 Vampiric Tutor
4 Phyrexian Dreadnoughts
3 Illusionary Mask
1 Explosives
1 Mox Sapphire
1 Mox Jet
1 Mox Ruby
1 Mox Emerald
1 Mox Pearl
1 Lotus Petal
1 Black Lotus
4 Polluted Delta
1 Flooded Strand
3 Island
1 Swamp
3 Underground Sea
3 Wasteland
1 Strip Mine
Board:
2 Anull
2 Old Man of the Sea
1 Hurkyl
1 Echoing Truth
3 Yixlid Jailer
2 Chains of Mephistopheles
1 Extirpate
2 Pithing Needle
1 Engineered Explosives
Cut the Psionic Blast as the 61th card, which was just for surprise reasons and then we have decks that are very, very close:
-2 Spell Snare
+ 2 Mana Leak
Just a metagame call as we do still have a big amount of Staxx and Storm and not that many GAT and Flash
- 2 Cutpurse
+ 2 Merchant Scroll
I leave it to you, which choice for card advantage is the better. I think in a field full of creatures/blockers and in a deck, that very often operates just with two mana on the table, I don't like the cutpurses that much. If they worked out for Tommy, great! I just think as close the disruption package is to SS: In the end this deck plays out different than just SS with Noughts. While SS is a pure control deck, this is much more aggro control. And for instance, if there is a Nought on the board, I would rather see a Scroll than a Cutpurse.
- 1 Duress
+ 1 Daze
Sure, four Duress is a great threat against any Combo. But I prefer a good mix of disruption spells, what is good just alone for psychological reasons. But Daze can also be a handy tutor target in some situations.
- 1 Trickbind
+ 1 Illusionary Mask
This can be for sure a good move in Flash heavy metagames. But Flash is a deck I don't fear with this at all anyway, and again: Mask can be very good against Staxx and sometimes against counter heavy decks as well. But Trickbind is for sure a great card.
- 1 Tinker
+ 1 Explosives
Tinker cost more than Mask, cost you an extra card in form of an artifact you very often don't have, is REBable and finds you in Tommy's build just Mask or Lotus or Dreadnought, which you then have to stifle. That all for the Collossus in the board and sometimes to go around Chalice Two, I am not sure, if I like that. You can go around Chalice with Stifle anyway, to bring in Dreadnought or bring in Mask. But the Collossus in the board might have good uses against heavy artifact removal decks. But I often tried to force Tinker in this deck as well, as I thought it's impossible to leave this powerful card out. But in the end, it never seemed to fit.
Explosives rounds up the disruption/removal base perfectly, as It handles Welder and Moxen very smooth.
- 1 Mystical
- 1 Mana Crypt
+ 2 off color Moxen
Yes, Mystical is great in this deck, and I included it meanwhile as well, as it finds Time Walk (and meanwhile Yawgmoths Will as well). Mana Crypt can be good to bring in the first round Mask + Nought. But I rarely go for this move. I think the best move you can do with this deck first turn is to play a Confidant, which functions well with the whole set of Moxen. Beside the first turn Mask + Nought I don't see really an overwhelming reason to play Crypt instead a Mox, as even in that deck with such a low average casting cost life loss summs up, especially in a field full of attackers. But Crypt is ok, if you want to run it, but I don't think it's really necessary.
- 1 Bloodstained Mire
+ 1 Flooded Strand
Against the decks, I need Basics the most - Fish and Staxx - after boarding the basic Island get even more important, as the main weapons out of my board against them are blue, and Duress gets out. Tommy plays Edicts. And Confidant is also a good move against both decks, so his choice of Bloodstained might be the correct one for him. I prefer to have more possibilities to get basic Islands.
I don't look at the sideboard, as these are usually even more metagame calls, but I do questions Rebuild (?) and the extra Cutpurses in this deck.
And here we are! That are the differences of the decks. They don't seem that big to me
So I'm sorry Steve, I don't want to be offending: But I see no reason to say, that no deck before had Tommy's innovative edges or even looked like hims. Thats just not true and disappointing for me, who put much effort in this creation, presented it on TMD and didn't get any attention at all from any one of the established TMD members. And now, that there is some player of the US team circles coming around with such a similar deck, it shall be new and innovative. I don't understand that.
I totally believe, that Tommy created his deck just as he described and didn't use any other build. It's very important for me to underline that, as I don't want to accuse Tommy for anything at all. That it came out that similar way has an obvious reason: He must be a good deckbuilder and these lists are already very close to an optimum. But to me it seems to be a tough call to say it's unique and it would be very nice if these "scrubby" european metagames get if not respect at least a little bit more attention sometimes.
Thanks, peace and again: Well done Tommy and very interesting card choices!
