Mystique (Shapeshifter)

Changeling (This creature is all creature types)
{1}{p/u}{p/b}: Search target player's hand, library, or graveyard for a creature card. Mystique becomes
a copy of that creature, except it's activated
abilities cannot be activated. Put that creature
card into owner's graveyard. Use this ability up
to twice per turn, and only when you can cast a sorcery.
