I know it's expensive, but Boros Reckoner is AMAZING for this deck. He contributes 3 Devotion, and holds his own as a nasty critter.

Check out my Fanatic of Mogis deck here:

Deck is 62 cards and the curve is quite i would suggest adding more mountains and reducing your curve. agree with reckoner i think u should test satyr firedrinker or whatever its called. if this is a bte deck, u need more bte compatible critters. id relegate the 4 drop devotion card for now and madcap skills to make room

Young pyromancer has a lot of synergy here

Young Pyromancer was a big piece of the original version of this deck but with only 12 instants and sorceries it doesn't merit inclusion. I haven't had trouble with the curve at all and being flooded with land really screws this deck. Firedrinker Satyr strikes me as an awful card with no upside. The only benefit is a 2p creature for R. but with Rakdos Cackler I get a 2/2 for R

By the way, take another look. Rakdos Cackler is already in the deck
