This card is too powerfull, I think. And I also think it doesnt fit correctly to the name "pandemonium", at least in upped form. Not pandemonium, just a mass enemy creatures control.
How about a negative (chaos seed) / positive (chaos power or upped mutation) to both yours and your enemy creatures? The upped form could cost less quanta, then. This would be really chaotic / random / pandemonium, like the entropy theme (although I think most people would prefer the mass creature control, people are even planning use it in rainbow instead of RoF).
Well, at least, I think upped form should cost 7.
