well, my strat:
-I summon my aeons to take the hit when he uses ultima.
-I use Yuna, mainly for the aeons, Lulu, because she can double cast, and Rikku, who has equipment that wards all 4 elements that he uses
-I summon the Magus Sisters who are often a very valuable asset against seymour. Anima, when summoned with a grand summon, is helpful but i find shiva much more helpful.
-Sometimes i have Lulu use white magic and Yuna use Black Magic.
can anyone see a flaw here that i can fix?
