I am pretty sure lightning main combined with Ay, Samui and Minato Jonin work pretty well due to the amount of chase which helps minato's damage, but it's mostly used to do a lot of damage quickly (2 rounds).

Again it's made for pure damage, it has barely any resistance and defense, I put main in open instead of minato because you can really make your main way tankier with life boosts and such, like my main for earth goes up to 20k hp alone and my lightning main goes up to 18k alone. Not even on a life tactic circle.
