So this means Creeper can't negate himself, correct?
And I'm a monkey's fist, but why can he negate himself? Creepers aren't considered people? (characters)
He can't. I was trying to be clever, but I might have made it a bit confusing in my attempt. I said "I'm a frayed knot" in response to the question, which I interpreted as "Can CD negate himself?" However, if the question was interpreted "Is it correct that CD can't negate himself?" then my response of "I'm a frayed knot" would be wrong.
In case I'm still being confusing:
CD cannot be negated by character abilities or enhancement abilities, including ones used by himself. He can be negated by Iron Pan, but there's no card I can think of in the current game that can negate him.
