I've been playing Magic with my boyfriend and I wanted to cast Complete Disregard (CD) targeting one of his creatures, but my question is, does CD work with base power or with power after alterations?
Specifically: the creature I wanted to target was Impostor of the Sixth Pride acting as a Sliver creature, with Cleaving Sliver giving it +2/+0 and also with a +1/+1 counter on it. Now, I am pretty sure that the +2/+0 obtained from Cleaving Sliver matters more than the +1/+1 counter, still, would Complete Disregard work on it?
