Persian Speedwell looks pretty good, I think it's time for me to upgrade my Debrobium team, I think this team is falling behind compare to my Knotweed and Corbett team, current team:

Debrobium
Ume
Honeysuckle Parallel
Colchicum
Ash

I must be doing something wrong with this team because atm they aren't doing anything worthy, just Knotweed + Corbett vs world, and they team barely do any damage in the EX map of current event, they just do about 2/10 HP of mobs and then die despite being a turn 1 team too.
