Ace Flockbringer

Whenever you cast a noncreature spell, create a 1/1 white Spirit creature token with flying. This ability triggers only once each turn.

Flying

Creatures you control have "Whenever this creature becomes the target of a spell or ability, reveal the top card of your library. If it's a land card, put it onto the battlefield. Otherwise, put it into your hand. This ability triggers only twice each turn."

Flying

Whenever a card leaves your graveyard during your turn, draw a card. This ability triggers only once each turn.

Flying

When this creature enters, choose a creature card in your hand. It perpetually gains flying.

Flying

Whenever this creature or another creature you control with flying enters, put a +1/+1 counter on target creature you control without flying.

Whenever you cast a white spell, this creature gets +1/+1 until end of turn.

Whenever you cast a blue spell, this creature gains flying until end of turn.
