The Chaos Keeper

The Chaos Keeper enters with a sealed Magic booster pack of your choice under it. (You provide a new pack each time.)
Whenever The Chaos Keeper deals combat damage to a player, reveal its cards and put one of them into your hand. (Don't open the booster pack until the first time this ability resolves.)
