Gatherer Card Rulings [Nov 2009]

• 5/1/2009: You may target a creature you already control.
• 5/1/2009: If you don't control the targeted creature when the "at end of turn" ability resolves, it won't be sacrificed. If it's still on the battlefield but under another player's control, the ability won't try to have you sacrifice it again at the end of the turn after that.
