Quixotic Quagmire Queen

Whenever Quixotic Quagmire Queen deals combat damage to a player, choose a nonland card name. Search target player's graveyard, hand, and library for all cards with the chosen name and exile them. That player shuffles their library. You may play cards exiled by Quixotic Quagmire Queen without paying their mana costs. (You can't actually access your opponent's hand, library, or exile zone.)
