Vish and Clef aren't even comparable.
You don't insta-lose to Clef by not having a hard counter. Clef is annoying for sure, and takes virtually no skill to use, but you can still play around it with a normal team, and mons can be introduced in the DLC to counter it and make it less good at its role.
With Dracovish, even if a new counter could be added in the DLC, all it will do is change it from every serious team having a party slot reserved for Seismitoad to every serious team having a party slot reserved for either Seismitoad or the new counter.
