About Crit Teams with Survivability:
I was thinking about a Hybrid Debuff/Crit team.
If the devs decide to release more girls of that specific Ability Combination (currently there are only Acacia, Herbaeceous Peony (Halloween) and Spring Starflower) i think you could literally break the game.
Some could argue that a few girls already broke the game so why not go down the rabbit hole a little bit further ?
