by the way... staravia, kakuna, metapod, silcoon, cascoon, luxio, ninorino, ninorina, flaffy, herdier, dousion, lampdent, delcatty, swadloon, shedinja, mawile, and sableye are allowed. their BST is 380 or less despite being evolved, with shedinja's bst being even lower then nincada's.
EDIT: oh my gosh did you even CHECK?
There's a reason why it was named as a 'Petit' challenge, and that a special rule was made for baby pokemon + their 'base' forms. Unfortunately, the explanation was omitted in this thread from the original. I thought it was unnecessary and just made the first post too long.
edit: you made me realize that I only had to insert two lines in the first post to have avoided that confusion, though. So thanks (and btw, Mawile and Sableye are actually in the
Bench section, since they're at their base forms)
I do understand what you meant/expected, though, and I was actually considering on remaking this challenge into the more-general NFE challenge to allow the pokemon you mentioned. Probably soon. I'm just getting the rules together and make sure they are integrated to preserve the challenge this thread has offered.
