Slight ideas on Creature Choices.

I second adding High Priest of Penance to the mix. I'd take out Aegis of the Gods all together to make sure this card sees play. Think of it as a 2-drop removal spell that doubles as a chump blocker, and with Athreos, God of Passage on the field, it'll force them to either repeat the removal or lose 3 life. If you have Xathrid Necromancer , enjoy that free 2/2 zombie token.

On that note, I feel like Underworld Coinsmith can be a bit too slow. With the number of enchantments you are running, it's certainly not a bad choice, but I personally cannot justify running 4 of him. This is just a personal opinion, but I'd rather more of my Xathrid Necromancer over my Underworld Coinsmith , just because Xathrid Necromancer adds more reward to your weenies dying.

The changes look good so far! Keep up the good work.

Also I would take out 1 or 2 Omenspeaker 's and replace them with creatures that provide draw instead of scry or some more removal would help.

I also think that the Angelic Accord 's really aren't going to play well unless you more life gain in there. So either add life gain or take those out. It all depends on what you want to do though if you like out lasting or straight up murder this deck can be built in either direction; but sadly not both.
