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.
Any effects that say that the Angel can't attack (such as that of Propaganda) affect only the declaration of attackers. They won't stop the Angel token from entering the battlefield attacking.
