Old units are quite garbage, their 8%-15% atk buffs are useless.

I'm not sure if I can even afford to summon Hinoki School + Swimsuit Usagigoke + Red Spider Lily (Higanbana) School anymore.

But I'm chilling because so far I my best team can beat EX with pretty much 0% to fail, I need to focus on getting quality girls.

Also Cat Cymbidium is rated as SS tier along with Hinoki School by Japanese players, truly so because she brings 3 attributes, skill activation x2, guts and act again. A really really good unit to have.
