Now it was a good time to beat Goddess Descended on Mythical for me.
Having Byakko at max level already.
Lu Bu, Byakko, Lilith, Hera, Hera-Ur, Ronia
All of them were useful. Usually atleast one or two wouldn't be used in my usual sweep(and that usual is Lilith, and Hera if not stalled long enough. And yes, I still haven't maxed Hera's active).
Basically this was the gist:
R1: Sweep
R2: Stall
R3: Sweep, but most likely you'll be able to stall a few turns
R4: Hera + Byakko + Lilith = Sweep
R5: Ronia + Hera-Ur + Lu Bu = Sweep
Thanks to Dark > Light, it was Ez Pz.

Why REM pull when you can save stones for useful stuff and hypermaxing?
When I was getting decent Gods from REM, I used to prioritize maxing them first if I was gonna use them.
But thanks to my "Big bust in REM of 10/18", I focused entirely on maxing my other monsters. Including 4 of same Mystic Knights of each set, which is to be used for Awakenings, instead of using TAMADRAS. Then there's the piled up Healer Girls, Golems, etc. Atleast with this, especially the Mystic Knights and Golems, I can finally use a decent Rainbow Physical and Balanced Team.
