So I'm trying to decide something important for the metagame portion of my article. Basically a lot of it mentions Starmie as a very versatile spinner. Here's the thing, Starmie has a Cosmic Power + Recover set, and the way I've interpreted CP it's +1 Def / +1 Spcl. Given Starmie's Speed, I don't know if that's even counterable if a set of CP / Recover / Blizzard / Thunderbolt is used. Victreebel and Venusaur can switch in once, but once Starmie gets to +2 it's all over. additionally, only Victreebel's Leaf Blade can OHKO, Venusaur's Razor Leaf falls well short. Zapdos and Chansey are the only things that can reliably stop it, and if it runs Psychic to lower Chansey's Special it becomes more vulnerable to other Psychics countering it, but can eventually overcome even Chansey as well.
So I guess it's technically counterable - but only if you know its set, and only if you have Zapdos, Chansey, or the Psychic that resists the coverage move it chooses (Eggy for Thunderbolt, Slowbro and other Starmie for Blizzard). And that's only one Starmie set - it also has its standard set, and a spinner set.
