I too use Crested Sunmare and it is wonderful! Especially with Seedborn and Trostani - gain life, triggers token, untap, populate, triggers get more tokens and more life
I honestly have enjoyed God-Pharaoh's Gift more than Seance. I've found that by the time I'm wanting to cast Seance (having enough creatures in the graveyard) that I can easily cast GPG and the token is a bit more immediate/sticks around.
Teferi's Protection has been great here as well as Rootborn Defenses and Heroic Intervention. Really great ways to protect our board state!
