I was thinking about this and Quantum Flash and I came up with something that might be too powerful, but is certainly incredibly interesting. I wasn't sure if it was original enough to post it as a separate card idea, and it'd need feedback anyways, but what about a card that protects ONE quanta pool from being altered at all(possibly for a limited amount of time)? This would let mark-based decks like Ghostmare protect their valuable quanta from BH, Devourers and Discord, give a bit of breathing room for monos, and let rainbows have a small amount of control over what quanta colorless takes. It seems versatile enough to be used in many decks yet not overpowered if its cost is balanced correctly. Anyways, just thought I'd bring up the possibility, see what people think of it, and if it's original enough from UTA's idea to deserve a separate thread.
