Tzeentch

When Tzeentch enters the battlefield, flip a coin for each nonland permanent type on the battlefield. Destroy each nonland permanent whose coin comes up tails and is not named Tzeentch. For each nonland permanent destroyed this way, its controller reveals cards from the top of their library until they reveal a card that shares a type with that destroyed nonland permanent. Put the rest on the bottom of that player's library in a random order.
