>>33316434Also I need to add this. This is a spreadsheet I found on Smogon that details all of the different types of Pokemon sets that exist in the Tree, and which trainers are programmed to use those sets.
As an aside, that Gengar set you mentioned in the first post is called "Gengar-1." It uses a Hypnosis strategy where it survives an attack with a Sash, uses Hypnosis, and then Dream Eater/Nightmare/Shadow Ball depending on what the CPU expects you to do next.
All Pokemon are programmed with 4 sets.
Typically this is how the structure goes:
Battles 1-10: All Pokemon used by NPC use Set 1 (19 IVs).
Battles 11-20: Some trainers use Pokemon from Set 1; others use Pokemon from Set 2 (23 IVs).
Battles 21-30: Some trainers use Pokemon from Set 2; others use Pokemon from Set 3 (27 IVs).
Battles 31-40: Some trainers use Pokemon from Set 3; others use Pokemon from Set 4 (31 IVs).
Battles 41+: All Pokemon used by NPCs use Set 4.
