I get that Elaine is here b/c she's a Normal-type (maybe EX-R Anabel would be better, idk), but maybe Larry would get more mileage out of any random aoe rebuff reducer like SC Lyra, SC Zinnia, NC Leaf, Adaman, etc. just b/c his Sync would at least retain his innate multiplier on the sides. Either that, or use his regular Hyper Drill on a side first (reducing weakness rebuff), and then use his B move on the mid and other side to reduce their Normal rebuffs so you can spread them out.

Not worth at all a normal team. You do it quicklier with mid tier suppereffective teams.
