However, in a squad with a couple of Activation Rate boosters she really takes off. Doesn't really matter if those boosters are rainbow or gold, but she's performs more like a weak gold card when put in the wrong squad.

This is why all of my Helper Squad members boost the squad's stats (4/5 boost Attack, 2/5 boost Defense) and FP is going to be swapped for Dianthus (less speed is made up for by a 3rd AoE skill + heal from pest node). Anemone is the only one who doesn't boost attack but she has received 99% of my ampys, her counter ability is nasty and her Skill coming after 3 AoE skills is good stuff ^.^

Buffing the already high stats of the rainbows, plus 3 Hit-All skills and a Hit Random x3, plus Dianthus' heal, Anemone's counter, Alpinia's self-heal... UBER NASTY SQUAD FTW!!!
