I want more 2 mana flyers and Spirit is great because it protects high impact 3 drops (Kiora, Tracker, Soultrader, …).

Priest is hate and synergy in White.

Provisioner and Ivora reward you with tons a trinkets and aren’t restricted by any clause.

Asmo is a hybrid for the discard deck.

Station is offers a combo finish in the right shell or can set you up nicely. Being colorless helps White with Phlage for example which I think is important.
