Zealous Conscripts, some of the new Dimir Cards...they take control of things.
Wait...just about everything with flying survives 3 damage. Sigarda, Restoration Angel, Angel of Serenity, Niv, Rakdos, Griselbrand, Thundermaw, any of the legendary Avacyn Restored Angels...Desecration Demon, Olivia Voldaren (if she's big enough)...
It's decent...it's just very very situational. And I'm not sure it's constructed playable.
