Thanks for the tips all, I beat it in 10 or so turns with a team of 6 since I didn't know what to expect.
I took WoL, Zarg, Rem, Ace, Minfilia, and a friend Dark Fina. I could have easily left Minfilia out and it wouldn't have affected the outcome at all. Really never was in danger, just healed up with Rem and did Tri-beam and Ultima +2. I was hoping Minfilia's Protection of the gods or whatever the auto counter heal was, would proc and free Rem up to Dagger Boomerang, but I think WoL took all the physical hits so she was useless.
Debating if I want to bother with the Water Resist. On one hand, i'd probably never use it. On the other hand, I have all the other single element resists already so maybe...
