Edwin's cards

Cryptivore's power and toughness are each equal to the number of creature cards in all graveyards.
, Exile two creature cards from any one graveyard: Return Cryptivore from your graveyard to your hand.

Target opponent chooses 'land' or 'nonland'. Search your library for a card, exile it face down then shuffle your library. Any opponent may say 'challenge'. If they don't, put the card in your hand. If an opponent does, reveal the card. If it's of the initially specified type, the challenging player loses 5 life and you put the card in your hand. Otherwise, the card remains exiled.
