u might as well take all those stats t 255 for how close u r.

i highl recommend using wakka and attack reels. but with those 3 have them learn entrust and enter battle with all overdrives. have yuna grand summon anima for oblivion and insane damage then (if u can) dismiss it before it gets killed. use entrust with the other 2 to grand summon anima again for more oblivion. if ur anima does die you can always use other OD's with high amount of hits (e.g magis sisters).

this is where wakka is good. the number of attacks is less but if he gets killed he can be revived, unlike anima

btw, blitz ace has more attacks than slice and dice.

of course there are the obvious tips that don't need to be said. i.e. fill everyones OD's (inc. aeons) before battle, etc.

but with those stats and oblivion (and attack reels if u can be bothered) it shudnt prove too dificult.

pd support magic is always a gud idea (particularly hastega and protect). u can cast shell of course but be aware that this will reduce healing amount.
