Took this from the VR because they go better here (they're fine questions, but don't wanna take up space in the VR responding). Electrode has Speed, and while it's seen little usage it hasn't seen none. You can see that it outspeeds some things Zebstrika can't, like Scarf Mesprit and pretty much every Shell Smash / Rock Polish user, by checking Speed tiers. Vigoroth isn't as bulky for sure, but having a fast Taunt does set it apart from Type: Null by beating other Taunt or Encore users. Not being shackled to Rest is pretty cool too. Duosion is like worse, but also not completely messed up by Spikes and Tspikes, which are super common right now. Overall they're all fairly niche, but that's reflected in being ranked much lower than their counterparts (well Trode is close to Zebra, but Zebra isn't amazing in the first place plus it might rise).
- Why are electrode, vigoroth, and duosion even ranked? Zebstrika seems like a completely better electrode, type:null seems like a completely better vigoroth, musharna seems like a completely better duosion unless I'm missing something.
- Why are 3 gourgeist forms ranked? Can't you obtain the other forms just through allocating Super's speed evs?
As for the Gourgeist formes, you can't actually get the exact same thing. Small has the base Speed to set it apart for a subseed set, and the Average form has the best mix of power and speed for z-trick-or-treat. Only Gourgeist-Large has absolutely no niches. What you can do is modify Small or Super to get the same defensive stats as the other two, which is why we only ranked Small and Super last gen, but now Average's stats happen to best fit the new Z-ToT set so it gets to be ranked as well.
