Even if the aether quanta wouldn't cause any trouble, I'd still not rely mainly on Twin Universes. The most decisive part of a match, is how long it takes you to get one copy of each weapon out. Once you got one of each out, you start gaining control of the battle field. The second EE makes things easier, but the fourth or fifth weapon usually just fastens the game. Therefore you're better off, the faster you draw at least one EE and Pulv. TUs (with, Puppy's magical aether quantum generators) would certainly make the deck faster, but would also lower the winning rate.
I never tried the fog shield, but from the description it seems a bit weak to me. I'll try it out, nonetheless. On the other hand, I start liking those diamonds better, the more games I play...
