Yup chopped him up in two mins with just squall here is how i did it..

Junction magic:
(in order of importance)
Evade (at least 25%)
vit
Speed
Strength
Health

Abilities:
Attack
Magic
Auto-potion
Auto-haste
Evade +30%
HP +80%

Magic:
Aura
Regen
Curaga

Then Squall is a killing MACHINE

side notes:
I always keep squal incredably strong and the rest, not so much, so they died on the way there.

Even at around 30 evade almost nothing can hurt you with physical attacks.
(my guy had 45)

Good vitality keeps his meteor from hurting you much but if you have regan and curaga he can barely touch you.
