So this would work just like a normal random battle, but with no switches. This would make random battles more challenging as if you were matched up against a stronger pokemon, you may have to work with what you have instead of switching. I believe that this would make this type of battle more interesting; people may need to use different tactics and strategies to make it work and for them to clinch victory.
If you don't like the idea of it being Random Battle, then there could be a Switch-Less (or No Switch Battle) format where people have to create lots of different teams and outcomes to try to make the perfect team and perfect pokemon for any circumstance. I hope you like it and find it an interesting idea. I also believe that it would be easy to implement, as only one aspect of battles really needs to be removed. Thank you for reading :)
