Well this funny stage is somehow a tiny bit not easy. It's doable until 5th fight with thoses -90% skill rate pests. I can pss thoses with Tritoma to finish them but I lose my best team in this process. It won't do it until I find a reliable way to beat them (who's not called modern counter). I don't think good old evade team can do the job. And I have to manage speed with precision to get the teams in the right order...
Gacha with limited gacha girls only. Cool. But no ancient knights, world flowers or Riko. Seems some girls are more limited than others
