I was often convinced this would backfire quickly even in multiplayer, so ignored it, and a friend used it in his human deck.

Foolish, foolish me. The begging you will do when things go south and the player with this becomes a bloody Arbiter. Don't forget, the destroying of the attacking creature doesn't even have to be one attacking the owning player... so if you have this, you can save an opponent AND give them the two cards. That's how you make friends.

Evil, brilliant card.
