IMO, Lavender is still a very solid choice in my solar blast team. While not a full team yet, with Violet, Ivy, Lavender, Convallaria, and Strawberry candle as filler. I can mini nuke with 20k damage. Not much, but enough to clear any event enemies out except boss. And with the 4 girls generally good speed with Ivy at top700, I never suffer from lagging behind the rest.
