Why not pick 3 random pokemon and turn yourself into a chimera of them? To pace it out, you'll only start transforming into a pokemon once its picked. Skips are allowed, but make it so you have to end up with +1 total pokemon in the chimera each. (I find the pokemon.com site's pokedex page is good for getting random pokemon)
Wowzers there are a lot of these little guys now! Anyways to answer your “why not”: Because I keep skipping them like a little baby! I decided to be funny and skip until I got a funny trio and ended up with Purrloin, Litten, and Glameow, though. Los tres gatos. Wouldn’t mind turning into a fusion of them, I suppose!
