Farewell to Arms
Enchantment
(CMC 3)
As Farewell to Arms enters the battlefield, choose a hand attached to an opponent's arm.
When the chosen hand isn't behind its owner's back, sacrifice Farewell to Arms. If you do, that player discards their hand . . . of cards. (The lawyers wouldn't let us do it the other way.)
