Zolvander, the Summoner

Flash
{2},{t}: You may create a 2/2 blue spirit with flying, a 5/5 black demon with flying, a 1/1 red goblin with haste, or a 3/3 green beast token.
If you control three or more of each token, you may shuffle your hand and your graveyard in your library. You search for three cards and put them into your hand.
