Terra, Herald of Hope / Kaalia the Vast

I have upgraded the [[Terra, Herald of Hope]] precon a bit and added cards like [[Aurelia, the War-leader]] and [[Liesa, Forgotten Archangel]] and had a lot of fun with those two on the field.

I was wondering if it would be possible/anyone had recommendations on how I could add [[Kaalia, the Vast]] and other cards to this and turn it into an angels/demon/maybe dragons deck but still have the graveyard recursion that Terra utilizes as a main focus of the deck. Appreciate any insight.

Here is my current deck: https://moxfield.com/decks/JWDTq-BYF0-gbc_CEMMDfg

Thanks in advance!
