Dahlitra, Patron of Mages

Whenever you cast your first noncreature spell each turn, discover X, where X is its mana value. (Exile cards from the top of your library until you exile a nonland card with mana value X or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)

Each other Shaman, Warlock and Wizard you control enters with an additional +1/+1 counter on it and has haste until end of turn.
