AI, switching, and immunities

[Aeodyn 18]

No errors, but some bad choices by the AI.

In the Grand Hall, I start with Scrafty against the Prankster Meowstic-M. I've seen it try a few different things:

• Psyshock 3 times in a row, despite Scrafty's Dark typing granting immunity to Psychic.
• Light Screen 3 times in a row.
• Thunder wave twice in a row, despite Scrafty's Dark typing granting immunity to moves boosted by Prankster.

Realistically it should do Reflect and maybe Light Screen, then switch out. Instead it lets my Scrafty Bulk Up to +6.

 

A much smaller thing is that I think the AI, when using a choice item, should deprioritize moves that the player's team has known immunities to. Currently it's very easy to, say, bait with Aggron then switch to a Flying type against Earthquake.

Same with High Jump Kick, baiting with Aggron and switching to a Ghost repeatedly.
