>>50832297I was curious so I tested it out. Both are 5/5 with their respective grids built to help maximize damage. Both also have their Sp.Atk and crit maxed out. ALSO also, I'm using maxed out 3* gear for their respective typing to add more stats.
>Giovanni teamI used EX Sabrina's sync first on a sidemon so the team would get access to the damage boost. I then hit Will with one Shadow Ball and got 9,968 damage. Note: Mewtwo is not under the effect of Red's Super Effective damage boost. He's only on the team so I could sync faster.
>Fantina teamI stuck her with an all ghost team for the purpose of giving her extra stats from theme skills. I synced with Fantina and the damage was 9,871. Funnily enough, I actually had to reset the battle since the sync move didn't crit, and only did a measly 3,000-ish.
Fantina has to use a sync move just to barely match the power of a normal attack by Giovanni. It's pretty sad.
