Ok, I have a Blowfly Infestation in play. My opponent plays Disenchant on it. I respond before Disenchant has resolved and play Scar on his 1/1 creature(doesn't matter what creature). Scar resolves and his creature dies since it has a toughness of 0 now. Does Blowfly trigger, allowing me to place a -1/-1 counter onto another creature before Disenchant resolves, or does it resolve first, keeping me from placing the -1/-1 counter? Thanks!
