Effort Values. You train your Pokémon beating specific Pokémon to make your Pokémon stronger: 4 EV's give one stat point. You can add 510 Ev's to a Pokémon but only 255 in each stat. That means you can add 63 points to 2 stats or distribute them in any other way. I only want EV trained Pokémon so sorry. It's a no to your offer.
