I played a few test plays and it seems like a turn 8-9 win, if you draw a good hand, only thing i can suggest at the moment is putting in Jungle Shrine instead of Boros Garrison purely because its the same thing except you don't have to return a land to your hand, and if that is the only land you have you would have to return right back to your hand sense its the only land you would have, at least that's what i figure you would have to do.

Jungle shrine has green?

and also boros garrison is tap add white and red.

jungle shrine is add white or green or red.

Oh snap i didn't even notice that, haha didn't notice it gave 2 mana, my bad ignore what i said before then. lol

I swapped those 4 into 2 Rugged Prairie and 2 Sacred Foundry

Braid of Fire doesn't really fit here. Are you trying to use the mana to pay for instant-speed buffs?

It might speed the deck up to drop card:Victory's Herald.

Rather than card:Mirrodin's Core, use Battlefield Forge , Rugged Prairie , or Clifftop Retreat . These lands provide colored mana on-demand, rather than after charging.

Keep the costs in the deck low and it'll be much faster.

Definitely include Lightning Bolt and Lightning Helix . They work as removal and direct burn, giving you a lot of options in each game.

Rally the Peasants>Trumpet Blast just a note to consider haha

AEther Vial?
