Someone asked how to kill a morphed dude on Tabak's Tumblr. This usually works.

I feel like it's narrow enough to cost less.

Could, in theory, include the words "or if it has morph". It would be one of the few spells that morph creatures couldn't properly respond to... and give it some relevance compared to Doom Blade (Not much. But you get the point.)

@jmg: That's what it says. I used a denser sentence structure but it's grammatically the same.

Interesting to note that this doesn't kill manifested creature cards.
