By this time, you *should* have bahamut - he can break the damage barrier, you *should* also have the customize ability so that you can create armor to neutralize the effects of Zombie and poison... stone also if you have an empty slot. I simply equipped Auron with the aforementioned armor, and beat her up with physical attacks until her last form change, then I revived Yuna and used bahamut's overdrive, released him, called him again using the grand summon. The two mega flare attacks caused enough damage to get rid of her for good.
Haste is a good idea, but avoid casting reflect on your party as Yunalesca will recover herself instead of thinking she's damaging zombies.
