Black White DevotioToken/Control and enchantments?

Hello all, I was fiddling about the other day with my "old" black white extended deck, added some Theros, tweaked some stuff. But it's still in Extended. My playgroup doesn't really care what format, but since the retiring of extended, I was looking for some tips on how to fit this deck into modern.

The idea here is control of the board, draining life etc. while playing enchantments to boost Ethereal Armor, give Lifelink etc. and at some point swamp with creature tokens with overlord tesya and requiem angel.

It's super jank, and all these strategies kind of feed each other, but end up being pretty inconsistent. That said it's still fun,and this is all cards I had at the time from packs etc.

Any help of what to do to make it more even would be appreciated.
