The sequence for this fight was Zap Cannon on Xatu while it used Psychic to KO/disprove Judaism. I'd eat the Synchronize Paralyze, as Xatu uses its turn to Hyper Potion itself, and I use X-Defend to tank Claydols next Earthquake. I then heal the Para, then set up an X-Speed and X-Accuracy along with as many X-Attacks as I can before running out of potions while healing in between attacks. Then it's all up to flinch hax/OHKOs, which is a little more reliable with a 100% plus accuracy score for rock slide.
Had one attempt where Xatu literally ran out of psychic PP before getting a single Para. Claydol also wises up and starts using Psychic after awhile, bypassing X-Defend in the process. No X-Sp.Def in Gen 3.
This was very very difficult.
