Yipe! Combat damage? Because this is one hell of a combo with Power of Fire targeting itself. Truth is, that isn't even broken if you want it... just very funny.

Better with Power of Fire targeting the opponent's Saprolings and 3/1s, I'd have thought.

Heh, well, yes. I was just trying to be as absurd with this card as I could be. But the potential for abuse is always there when you don't add the word "combat" before "damage". Again, its not really broken, per se, it just makes the cards you design get used for different reasons than your original impetus.

Since the range of targets was so narrow, I opted out the comat damage for any lethal damage. Within the block I don't have too many artifact creatures for it's ability to be too good. Against the right deck it could've abused, yes, but overall unless you're goal is to combo this with Mycosynth Lattice I think it'll be okay.
