Well for the best boost u need lightning and water nin only (lightning only if u want the best possible team)
So that cuts down the choices a lot.
Now do u have higher or lower initiative than most people.u face?

Ok in that case we can assume.that most.of the time your Field will.last now which types.of teams do u like working with?
Blistz, control, stall,debuffs,dot,etc.
Which do u like cos if u know a type better u c*e it properly.
How u use a team is almost as important as the team it self
2 people.with same team and stats if 1 knows the team well came c*e it to its best it will be a massacre.
