I think personally, Kingambit does more good for the meta then bad, specifically when it comes to Ghost spam in general. IMO Kingambit was manageable Pre-HOME there was 0 activity prior to the release of HOME of it being suspect tested. With the release of HOME it's gained more "checks" then before. Tera in general makes the good mons better than they already are and I feel like Gambit falls victim to that. Again I don't like beating a dead horse but Volc really helped with the Will-O-Wisp sets (Flame Body in general) and that's why we're not seeing Tera Fire Gambit as often anymore.
