lightning main with serpent summon and Lai-Giri, GNW Hinata or regular Hinata, choose which skills you like, either acupuncture for 3 rounds if chase successful, or for one round but with 3x hits from mystery, then who ever you want with High -> Repulse, Kimi, Chojuro, Sasuke, etc. Or, Sarui and any knockdown to lowfloat or highfloat with Flood Dragon and Chidori Sharp Spear...
Sadly Water main and their meta teams are too OP for light main, light main now is as weak as you can get from all three, there is no meta team for light team so it's a pain in the ass, it requires high dmg and high initiative to even beat those that are higher than you in end game...
This comes from a free to play player...who can't do * in late game anymore.
