Xanathiel, Host's Vanguard

Flying, Vigilance, First Strike
Whenever Xanathiel, Host's Vanguard attacks,
create two 4/4 white Angel creature tokens with
flying and vigilance that are attacking.
Whenever one or more other Angels you control
die, Xanathiel, Host's Vanguard deals damage
equal to it's power to any target and you gain
that much life.
