The Deck of Many Things

At the beginning of combat on your turn, if
the Deck of Many Things is attached to a
creature, exile the top card of your library. If the exiled card is a creature card, until end of turn, equipped creature gains all abilities of that card
and gets +X/+Y, where X is that card's power
and Y is its toughness. Otherwise, sacrifice
equipped creature.
