Card of the Day - Exchange Favors

So Hollee said to me tonight, "Are there any bargain cards? Like a card that can let you trade a card in your hand with a card in an opponent's hand?" 

I thought for a minute and couldn't think of one, so I made it.

I had to rejigger the wording to make it mutual exile instead of just trading cards in hands, but if it makes you feel better, you can put that card in your hand if you like.  I give you my permission.
