I believe that's sewaddle
I never do/liked Nuzlockes, the sheer handicap of potentially losing a pokemon permanently is the biggest turn off for me. That, and only being able to have a limited amount of party members. Any given moment could be game over for your fateful ally,kind of like reality, which makes me...sadit kind of singlehandedly turns the game into Fire Emblem...Don't get me wrong, as much as i enjoy that game too, it has moments that are just...Arrgh!
I'm doing it as a form of challenge as the game offers none until the post game(its still fun though). I don't plan on releasing my pokés but storing then in the box 1 to transfer then to my Y version. I'm also using pokémon I'd never choose to use (like sewaddle lol) and I'm liking then.
I'm also close to earn all Gen 4 competitive shiny starters, I'm only missing Piplup (which I'll get from a trade). I'm also only missing Mudkip for gen 3
