Slicer, Hired Muscle

More Than Meets the Eye 2R (You may cast this card converted for 2R.)

Double strike, haste

At the beginning of each opponent's upkeep, you may have that player gain control of Slicer until end of turn. If you do, untap Slicer, goad it, and it can't be sacrificed this turn. If you don't, convert it.
