Prophetic Prism feels pretty weak. Maybe I'm missing something though. If you think its good I wont argue because it may well be. I would run 4 Aether Swoopers instead. They're decent hp budget blocker, with an ability to create more blockers, and they're a way to vent energy from other cards.
I'd also run 4
Stasis Snare or some other for of control to specifically use against enemy flyers so
Aether Swooper could reliably create servos, or generally just anything you can't handle otherwise.
