Discard a card: Search your library for a card with the same mana value as the discarded card, reveal it, put it into your hand, then shuffle. Activate only as a sorcery and only once each turn.

Exile target instant or sorcery spell you control. Until end of turn, you may cast that card from exile without paying its mana cost. When you do, copy it. You may choose new targets for the copy.
