I didn't have great luck with Satyr Firedancer , either. Great in theory. Deck gets +1

Chandra, Pyromaster could possibly be taken out if you wanted to put Purphoros, God of the Forge . Chandra, Pyromaster just doesn't pop up often enough for her use in the deck. Also if your go against a mill deck she is useless because the only ability you can use is her +1 where you get to deal one damage. This is just from my short time playing. Please correct me if I'm wrong.

I used to have Purphoros, God of the Forge in this deck but but found that the creatures coming out didn't make it a win condition and i hardly ever got to the devotion to turn him into a creature either. so chandras ability to draw a card went in its place. and if by a miracle i get to 7 I can usually win the game that way.

You make a fair point,but I would personally still sideboard something for Chandra just in case you go against that mill deck because her -7 ability only hurts you unless you get it early in the game. Overall though this deck is amazing and destroys the boros deck I play now.
