Yeah Yunalesca was kinda difficult for me, since I didn't take the time to recharge my aeon's overdrive after the previous boss battle. All I can say is this: make sure two ppl have Zombie in their status and one without, so when she kills everybody with Death, only one will go down instead of two or three. She'll use Zombie a lot but her magic isn't so strong. THat's the good news. Don't be afraid to have a bad status on your characters. Better than death, yah?

The phoenix down trick is a hoax btw.

Aeons. Whoever said she's vulnerable to ice...blah! It's not as great as Holy magic. Luckily 4 out of my 7 characters reached the end of their sphere grid: Auron, Rikku, Yuna, and Lulu. But with the magic booster and half MP, I could only cast Flare 3 times. Oh well. If you can, save Bahamut for last and be sure she's somewhere around 20,000 HP left before using it.

Isn't her final form scary? Rated PG game my arse.
