Adel is crazy hard. Ultimecia can be pretty easy if you approach it right. in case you don't want to do it an easy way Get Squall's Leonhart weapon, get a bunch of Aura spells, card mod Bahamut's card to 100 megalixer's. I think I had 100 Curaga junctioned to the HP to make that pretty high for my characters. Have one character casting aura on squall, one character tossing megalixers each turn, and have Squall using his limit break every turn. Gets the job done fast. Of course, getting the Bahamut card involves the painful process of fighting a bunch of ruby dragons in a row to fight Bahamut, and that's an annoyingly hard process, haha. Keeping one person throwing other healing items every turn should work though.
