Who should I go for this time...
Sensitive plant passive is op, not to mention she is a few blunt rainbow.
Easter Cactus has one and only unique passive, resurrection. But her status is really low for rainbow.
Kuro-chan/ Shiro-chan normal ver. for starting crit team.
Purslane for tanking and regen unit.

Guess I'll will just get the ticket and kept it for now.
