i think it would be better to replace supernovas with something else... against anything besides a rainbow or many-coloured deck, the supernovas wouldn't be all that useful. An aether mark would probably be beneficial, and SoG's would definitely help with stalling. also, maybe adding an aether nymph (or a nymph's tears or 2, because you have quantum towers) to immortalise creatures would be useful? Just throwing some ideas out there.
