Legendary Creature — Spirit Cleric
2 / 2
Hexproof (This creature can't be the target of spells or abilities your opponents control.)
Whenever Geist of Saint Traft attacks, create a 4/4 white Angel creature token with flying that's tapped and attacking. Exile that token at end of combat.
If you create more than one Angel token (most likely due to Doubling Season), both are exiled at end of combat. On the other hand, if something else becomes a copy of the Angel token, the copy isn't exiled.
