||At end of combat, for each creature you controlled at the time it dealt
combat damage to a player this turn, copy a random card with same mana
cost at that creature. You may pay (3). If you do, choose one of those
copies. If a copy of a permanent card is chose, you may put a token onto
the battlefield that's a copy of that card. If a copy of an instant or
sorcery card is chosen, you may cast the copy with paying its mana cost.
