Flying

Whenever you cast an enchantment spell, put a +1/+1 counter on Blessed Spirits.

Whenever one or more creatures you control and/or creature cards in your graveyard are put into exile, you may choose a creature card from among them. Until end of turn, target token you control becomes a copy of it, except it has flying.

+2: Surveil 2, then exile a card from a graveyard.

+1: Create a 1/1 white and black Spirit creature token with flying.

−2: Exile target creature you control. For each other player, exile up to one target creature that player controls.

Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for or one mana of that creature's color.)

Create three 1/1 white Spirit creature tokens with flying. (They can't be blocked except by creatures with flying or reach.)
