I would go with Toad lily, Convallaria, Edelweiss, Alpinia and Mountain Lily, decent speed (you can swap Mountain for Star for more speed) good balance of aoe/single target skills and sick sustain, with Toad and Edelweiss you have more than enough sustain so Lavender isnt needed imo, besides her speed sucks, also i would put them in the same order i wrote them, that way you let your aoe skills damage some pests/boss and Alpinia with Mountain can finish them off with their single target skills
