There are a bunch of maybe phyrexia cards. Dinosaur, Nissa, Defectormite, Conduit of Worlds, etc.

I think all of those would make the cut if my cube was back at 540, but at 360-405 they just aren't needed.

Rabbit Battery > either a red one or two-drop too, but it's not on CC yet.

Plenty of other testable cards in the set, but none that blow me out of the water.

Adding cards back that I was forced to cut because I can't have them on MTGO

Debating if I should re-add Demonic Consultation and Paliano Vanguard. They're fantastic cards in the list, but they almost feel like un-cards.
