Dracovish is amazing. Would highly recommend. To give you an idea, on my singles battle tower team, it's Eternatus, Zacien, and Dracovish. I've gotten well over a hundred wins, never lost or even come close to losing. Of course that's with a choice scarf (won't be available till Ballonlea) and max EVs in speed. Without that, Dracovish is still good, and definitely works! But other options (including but not limited to Seismitoad or Wishiwashi, among many competent others) also work. If you get a Dracovish with Strong Jaw, I'd go that route. Otherwise, keep what you have, or try something else, Dracovish at that point in the game would likely not be anything special.
