Klaw, Master of Sound — Marvel Super Heroes Commander #46

Deathtouch

Whenever you play a card from exile, Klaw gains indestructible until end of turn.

Whenever Klaw deals combat damage to a player, look at the top card of that player's library, then exile it face down. You may play it for as long as it remains exiled. Mana of any type can be spent to cast a spell this way.
