It's actually worse than that. A PSNBow w/Aether Mark could easily pull off
2x Supernova
Pegasus 4|4
(Dive) 8|4
3x Time Travel+3 more Dives (64|4)
Twin Universe (64|4)
And the next turn, because the TU doesn't lose it's ATK right away, the TU'd Peggy would finish off a False God. This could be done with phenomenal consistency by turn 7 or 8, before most FGs could kill you. That's bad, and it's why the original SoR had to be nerfed.
If dive were fixed (thanks plastiqe), this card would be fine.
