Rules for my Pokemon black 2 run (I beat black tonight! Didn’t do that the first time I played back when it came out):

- Catch the first new (unseen) wild species on each route — it joins your team.
- Statics/gifts/fossils don't count, no forced rotation.
- when full, longest-serving member is permanently boxed

Clarifications: you can catch as many pokemon as you want, but every time you catch one you swap out your longest pokemon.

You’re only _forced_ to catch the first new pokemon on the route.
