So two questions (actually there's more but can't remember lol)

1 - If I have ~150 ampies of each type, and I have 3-4 girls I want to power up, should I max ampie 1 girl, then rest others, or spread evenly between all girls?

2 - In your guy's experience, for drawn out battles (3+ turns), what team set-up has shown to do most damage? What single ability type would you prioritize (Evade, counter, debuff, etc..?)
