Elk, tried your deck. Went 1-1. Wrecked a golgari deck that got mana screwed.
Then I got mana screwed against Simic. I lasted a long, long time though and got soul blade out which did nothing for a long long time. I can guarantee you that my willbreaker would have won me that game, big time. Soul blade feels very win more. If I had an squadron of thopters, I would have slammed him, but I would have been in a good spot there anyway. I needed to deal with his creatures and planeswalker badly.
I won't dismiss the deck yet since it won a game. I'll try it out another time
Hmmmm.... well maybe a few more spins will change that?
Regarding Soulblade; after some more extensive testing, I've come to realize that it is a win condition. There are definitely a number of games where I don't need to even play it but I'm quite sure now that it's not win more. It does a great job as an anthem (for everything, not just artifacts) but it also works just fine on it's own as a late game finisher. It continues to gain strength (in my hand) where my opponent has to fight my board. I can play out threats creating enough of a board state to maintain the beatdown role and then let them answer. Then continue to repeat the process until the pressure I keep creating is too much. Eventually when Soulblade does come out, they either can't answer it any more or I can trigger it the turn it's cast. If it gets to attack, it's even better (on it's own w/o activation it's a 5 turn clock and we both know by the time it's played, the clock is already much shorter than that).
My question to you is - if it came out in the Simic game, what was the Djinn doing? Could you not swing with it at all or was it a really stalled board? You also mentioned not having any thopters. Had they answered your tokens/aggro (I'm thinking things like Disperse/ Displacement Wave etc for Simic)?
You mentioned some creature concerns too. Beast had suggested
Fiery Conclusion which I've now been running two copies of (dropped one twin bolt and the Grid) and it's shored up concerns with the larger creatures (I still don't like that it's creature only for targeting but it does fill a gap). Did you have a chance to try that out in the deck too? If not, I'd suggest squeezing that in and seeing if that helps answer any of the concerns you mentioned.
As for walkers, that's the reason there's a couple Disperse in the list. Disperse is a catch all for things like tempo plays, saving your own creatures, pushing through damage, walkers etc. They are really meant for that key play in a game where you look back and know that play/turn changed the outcome.
Besides, I realize after posting my list, that I've yet again created something that someone else has already built (in this case - you!). Our lists are a small handful of cards apart and therefore should play extremely similar (and should contain many of the same answers you've built into your deck).
Anyway, don't give up on me yet. I look forward to hearing more about how it performed for you. Your testing feedback is always valuable and appreciated (not to mention it's been incorporated before)!
Thanks bro!
