>>44807936It is one team per Gen, but I keep my Wigglybro around. And Tangela/Tangrowth and Swampert pop up in a couple of Gens.
As for making it I just copy-paste the sprites into paint lol, it's not as hard as it looks. I've made a bunch of them before. I can't into real art so it's an easy way to make my teams look cool.
