Expecting a lot of control at States?
4 Burning Tree Emissary
4 Chandra's Phoenix
4 Firedrinker Satyr
4 Firefist Striker
4 Gore-House Chainwalker
4 Rakdos Cackler
3 Chandra, Pyromaster
2 Hammer of Purphorous
4 Lightning Strike
4 Magma Jet
19 Mountain
4 Mutavault
Outside of -2 Mutavault (because I don't have them), this was basically what I was running. It does have a good control match up, especially if you can have two BTE chains and a hammer on the field. However, it's weak to red devotion aggro. Anything running an Ash Zealot or Reckoner can basically stonewall you. Post board gets worse when they throw in Frostburn Weirds and their burn.
Against control, the main way I won was via Chandra + Hammer on the field.
Loosely you draw a mountain every other turn and send out all your guys to always have 4 to 6 power on the field in the meantime. I tried to hover around 5 to 7 mana.
I think your old list is better, maybe take out a couple cards for an extra hammer or two in the main board to make the control match up stronger. Rarely have I been upset to see a hammer. However, there's been times when I've been desperately searching for a lolhammer.
