I have a farming squad that is sitting at something like 1130ish speed lol. Dipladenia, Alpinia, Orchid and Anthurium in the same squad is some crazy speed lol. I prefer having my helper squad be all rainbows though lol, so I keep that at Anemone, Black Bacarra, Alpinia, Dianthus and Fritillaria. 3 hit-all rainbow skills, a hit-3 random skill + counter, a self-heal skill and a 10% heal on pest nodes is a very damn well-sustained team ; )

For this event, I could swap Alpinia with Kerria (also self heal but slower and no team speed boost) if my allies wished it.
