So it seems to me like everyone is trying their hardest to crack the standard metagame post-M14 (and post rotation, for that matter.) I don't know a lot yet, but I do know a few things.
Young Pyromancer is amazing. I have a prediction that post rotation, every other deck you see will have Young Pyromancer in it. Whether it's Boros Blitz w/ Pyromancer, Izzet w/ Pyromancer, G/R Aggro w/ Pyromancer, heck Aristocrats: Act II w/ Pyromancer--decks are going to use Pyromancer. I played in an M14 prerelease this weekend and had the utter misfortune of seeing him combined with Chandra's Phoenix (and molten birth for that matter... oh god, the memories.) Young Pyromancer is a card. For real.
However, I think the best shell that the Pyromancer is going to fit into is a token shell. The G/W token deck has been on the rise lately as a fringe tournament deck. It's had a fair share of successes, but to me it's always seemed like it was missing something--like 2 colors was maybe too limiting. I think Young Pyromancer solves this problem in many different ways.
For one thing, most token decks use instants and sorceries over creatures to make their tokens. Thus, Young Pyromancer has his fun. Turn 2 Young Pyromancer. Turn 3 Call of the Conclave (plus elemental) and a Wake the Reflections (plus an elemental). You just put 8 power on the board on turn 3. That's crazy. Not only that, but the interaction between Young Pyromancer and Lay of the Land is also pretty cute.
Even better is the fact that splashing Red gives the token deck something it didn't have before--burn capabilities. The token deck instantly becomes more offensive when it can burn away opposing threats and swing uncontested with everything you've got.
And speak of swinging with everything you've got, have you taken a look at Gruul War Chant lately? Not only does it give all our creatures +1/+0 (which can be game-changing with multiple young pyromancers out), but it also gives all our creatures minor evasion, meaning they probably have to throw their value creatures in front of the onslaught and a lot of damage is still going to get through.
Archangel of Thune. The new gavony township. This angel is quite awesome. Not only does it make racing incredibly easy, but it powers up your entire army in the process. That's just cool.
Now, it's not that I'm poor, but I really just don't like dropping $150 on 3 cards. Therefore, Voice of Resurgence (except for one that I pulled) is being replaced for Wayfaring Temple. I don't think this omission is all that bad, honestly. With the way standard is right now, playing a voice doesn't gurantee me the elemental in anyway with rest in peace, pillar of flame, and essentially four different oblivion rings in standard. With wayfaring temple, it's a guranteed */* and also has the bonus of populating on a hit. I'm not horrified at the lack of VoR.
I think this deck has unbelievable standard potential, and I would love people's advice to make it better! I'm trying to avoid using innistrad cards (except for avacyn's pilgrim and pillar of flame because I don't think they have any replacement yet) to avoid getting screwed over by the rotation, but I don't think that will be a problem.
Comments and suggestions are greatly appreciated!
