Hey, looking good! I'd change just a few things though.

1) Swap Wingsteed Rider for Fabled Hero . Yes Mr. Wingsteed has the pseudo-evasion that flying offers, but he just can't hit as hard as Hero can.

2) Add in Ethereal Armor . Seriously it doesn't get much better than that. I'd drop Chosen by Heliod for these.

3) Throw Sin Collector in the sideboard. He's cool, but you could be running more Agent of the Fates or Banisher Priest in that slot.

4) Consider Cavalry Pegasus or Xathrid Necromancer to the Wingsteeds or Door of Destinies . I can tell you've got a little human tribal thing going on here (my favorite), but Necromancer and Pegasus will give your dudes a bit better bonuses than the Doors will.

5) Holy Mantle . Its spendy but it makes your dudes unblockable and immune to things like Polukranos, World Eater 's monstrous ability.

Anyways, best of luck, and hope I helped!
