Maddy saw some nerd do a card trick on a train, and now she wants a rigged deck of cards.

It's a standard deck of 52, with one Joker and another card marked "Oblivion" featuring a demonic face. The backs of the cards are identical in their black and grey-patterned appearance. The faces of the cards are printed with a special ink, allowing any card she is touching to change into any other card in the deck with a single thought.

What's the damage?
