Jarlaxle, Drow Manipulator

At the beginning of your end step, target opponent gains control of up to one target creature you control. Put two +1/+1 counters on it and tap it. It's goaded for the rest of the game and it gains "This creature can't be sacrificed."

Whenever a creature you own but don't control attacks, you draw a card.
