Adrenaline is way too mainstream.
Accelerate Mercenaries, and use BBs on Mercenaries for more HP or as CC.
Chimeras mash all your attack and defense together, while bypassing BB delay. Good for ending/finisher.
and for a real challenge: a 60 card rainbow that doesnt use quantum towers(other towers and pendulums okay as well as immo and SN)

God this was annoying. Haven't balanced quanta yet.
It's slow, but if you have a good setup you'll usually win.
Sundials to stall, sancs for healing, eternity for locking/prevent decking out
FFQ+Hope for defense, Fractal+Dragons for win.
