The Toxel Trouble

I really would like to add toxel to the game, but I understand the limitations that come with his evolution line. Though an idea that I have is to simply make it a randomizer, with a 50 50 chance of it being amped or lowkey form, since wurpmle’s evolutions to cascoon and silicoon are already in the game. Could this help enough for them to be added into the next holiday cave event?

Wurmple has branch evolution, cascoon and silcoon are separate pokemon, not forms. The method has nothing to do with it
