Since I'm trying to figure out my final team, I was wondering, what did everyone else go with and why?
I'm leaning Yukari/Aigis/Sanada. Yes, it's a double electric weakness, but Sanada is immune. Aigis and Leader can get a round of buffs up in one round. Yukari fully heals the party for 11 SP. And with Sanada, he and Leader can get an Atk/Def debuff going in one round, too. Idea basically being to be +Atk/+Def at all times and the enemy is -Atk/-Def at all times.
But that's just one idea, and Junpei with he crit-fishing is also an option. Or Mitsuru with her debuff Theurgy.
