I facetabled when I read "no one uses RotA anymore"...
Anyway, I prefer standard HERO Gate, as opposed to Diamond "Destiny" Gate. Diamond Gate relies too much on Safe Zone and Diamond Dude's mills; I got beat to death by a TKRO because I didn't have a Monster strong enough to beat over/crash into it.
Also, Side Parallel World Fusion; Side 2-3 of them. I Side 2. If I play against Agents, I'll Main from my Side PWF at 2-3 complimented with D-Fissures so they have no ammunition to Hyperion/Kristya my face.
No one plays Future Fusion in HERO Gate; there's another build for that I believe. Also, no Rai-Oh, and 2 Veilers please, and if you're running Diamond Gate, you need 3 Safe Zones.
Thank you Pyro for this sick sig~!!
