This isn't for beating the game. This is soely and only for beating the Elite Four & Champion. You can bring 100 Pokemon with you on your adventure if you wish. However, this challenge is specifically for the Elite Four & Champion. It's almost something to do post-game.

OIC, was thinking that this was meant to be an entire run with only one Poke tbh. Still sounds interesting, I'll get around to this by the time I can find a copy of Emerald again.
