The OHKO combo looks nice, but one thing is that you need three types of quanta (light for blessings and/or pegasus, air for skyblitz and/or wyrm, and aether for parallel universe). Trios are usually too unstable. I would suggest quantum towers + supernovas, or aether pends and air pends with a light mark. It's also a good idea to add a few defensive cards while gathering up the quanta for the OHKO, maybe dim shields, wings, or shockwave/thunderbolt.
