You must mean 99,999.

I recommend using Trio of 9,999 (Use Mix, and I know two gambler spirits will do it other combinations as well but I can't think of them) Cast Hastaga first thing in the battle. Have Wakka have Attack Reels and use it. Trio of 9,999 makes all attacks do 9,999 and a perfect Attack Reels hits... I think its 12, but may be 15 times I can't remember.
That will do a good amount of damage...
9,999x12= 119,988 damage.
My favorite strategy is having Wakka have an Auto-Phenoix armor, and setting him on Comrade. Have Tidus or Rikku attack Shinryu counters killing them Wakka gets his overdrive and then instantly revives the dead ally. Do damage quick and pray he doesn't use his stone attack (forgot what its called) on Wakka.
Also entrust works (I like mine better you get to do damage that turn instead of wasting it at least 9,999 damage)

This strategy is for more underleveled characters.
