Oh em gee, delta G equals delta H minus T delta S! The horrors!
Thermos aside, relying solely on 6 attackers isn't the way to go. Plus, 4 SoFres should be enough for 1 in early game and 2 in mid game (pretty much what you need). Unless you want a crazy critical crisis, 4 is enough. The epis themselves are already beatstick-ish. 6 epis are also... a bit too much. Often is that 1-2 will be dead in your hand. i prefer a 6-5 or 5-4 line with my creature+buff (as in mummy grinder). Then, you can safely do a pillar/pend split.
Why pillar pend split? Because
dragons are one hell of a beatstick on their own. Although the crit damage is not as awesome as maxwell epi crit (18 more-a bit worse than the theoretical 5-5-5-5), it is now less reliant on the 2 card combos. Not even too much on SoFre, too.
Side note, Maxwell's Demon has something to do with negative entropy IIRC...
And yes, I remember when trying the deja-epi-sofre-momentum stuff, the dejavu seems to attack 5 times... is it intended, or do I need new glasses?
