I predict it will keep trying and failing without changing strategy until the team is so overleveled that brute force works.
Unfortunately, the only usable move is flamethrower with 15 PPs that will be exhausted.
Remember, if it starts using items, it can run out of money. And what then?
But yes, brute force might prevail in the end. Let's say it started elite four at 13k jev calls or 1.3 USD. I'd call it a "loss" if it crosses the 2 USD threshold. It's still quite cheap though.
- establish a composition
- train the selected composition to an appropriate level
- ration PPs through 5 fights
- ration items through 5 fights + globally (you can run out of money)
- maybe even switch the order of pokemon on the list? Poor Graveler
I'm not sure it can follow-through on this. Would be funny if it had to re-do the rock boulder puzzle. Guess I'll keep watching!
