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.
9/22/2011 You declare which player or planeswalker the token is attacking as you put it onto the battlefield. It doesn’t have to be the same player or planeswalker Geist of Saint Traft is attacking.
9/22/2011 Although the token is attacking, it was never declared as an attacking creature (for purposes of abilities that trigger whenever a creature attacks, for example).
