Coveted Prize Sorcery
This spell costs 1 less to cast for each creature in your party. (Your party consists of up to one of each Cleric, Rogue, Warrior, and Wizard.)
Search your library for a card, put it into your hand, then shuffle your library. If you have a full party, you may cast a spell with converted mana cost 4 or less from your hand without paying its mana cost.
