Is there a meta where pokemon aren't "healed" by default?

Eg, if you choose, you can enter the battle with guts pokemon pre-statused, pre-damaged pokemon to trigger berry procs at different times, endeavor and painsplit pre-allocated, and other random interactions that might be useful.

There would be some INSANE unbalanced shit in there (guts ursaluna comes to mind) but sometimes you want that kind of thing. I COMPLETELY forgot about gliscor, though.

Edit: another potential effect is abilities like torrent and swarm actually being usable.
