Heh, it's Bomb Squad :) But more interesting. It seems from Set Ablaze that you're intending all blaze counters to count as +1/-1 counters, along with the "5-or-more = destroy" rule. What would you imagine would happen to a 4/4 with a blaze counter on it if this Insane Pyromancer died? Presumably you don't want to remove the blaze counter since you might draw another Insane Pyromancer later. So perhaps the counters could be just +1/-1 counters?

The problem is that at the moment if I have two Insane Pyromancer out, then all creatures with blaze counters get +2/-2. Add a copy of Set Ablaze and they get +3/-3. Is that how you want it to work?

I didn't want to use +1/-1 counters because it could be like Fallen Empires weird counters like +2/+0 counters, but I was just thinking of it having an effect like Guise of Fire except working only when the pyromancer was on the battlefield (enemies are normally unfazed by fire, mage makes it affect them) and having multiples of them intensifies the fire, enraging and damaging them more.

+1/-1 counters seem doable, though, I'd like to see a whole block of them, instead of just on a one-shot card. I agree... +2/+0 counters are dumb. Even +1/+0 counters seem unnecessary, in that they don't add anything that a +1/+1 counter couldn't do. But simultaneously stretching in both directions by a factor of one? I can get behind that.

I was just going to see if I could get this cycle of red cards going in this cardset of mine.
