Final Boss help?

[scorptatious]

So I'm stuck on the final boss after defeating Trance Kuja. (Who was a real wuss BTW) I can't seem to beat him. Even with all my status protection abilities, his Grand Cross attack hits me with either Zombie, that fury status ailment, mini, and death. He also throws out attacks so quickly, that by the time Eiko can cast Curaga, it's too late for one of my party members.

I swear, this has got to be the cheapest boss I've ever fought against in a game.

Any advice on how to beat him? Help will most certainly be appreciated.

I've never been beaten by this boss but i guess Grand Cross is a little annoying, what you do simply is having the abilities auto-haste equipped on all characters (especially on the healer) and auto-life, (If enough then Auto-Regen as well) if you don't have it then i suggest leveling up more.
Steiner should be in your party using Shock or something like that, Vivi can use Flare (Reflectx2 perhaps), or Eiko's carbuncle/auto-reflect, your choice.
If you're having problems then maybe Eiko is more suitable then Dagger simply because she has better supportive summons and offensive magic.
