I like the first one more. Just my humble opinion though.
Have you thought about having a death mark, but using entropy pendulums? That would keep the deck fast, but more consistent. Only problem with that is that if the entropy pendulum is destroyed, youll have a hard time pulling of the combo. So perhaps a death pendulum, with entropy mark? Quantum towers just arent neccessary since you are using such low cost creatures. Id almost just say use entropy Towers instead so you can get those SNs out 2nd turn guarenteed when you draw a tower in opening hand. I just dont like those Quantum towers in there for some reason. all 3 out only give 9 quanta a turnm so it would take 3 turns to average getting 2 of each quanta.
