mei,mabui,gnw tenten,fm ( yes this is water meta team,but works just fine with fire main,and even better in some situations)

fire is the most versatile main in the game,so possibilities are endless.

that one works with water the best,but yah it's a good counter against water meta.

then go water main for Ao,chojuro,mei team.
