>>57202120Ariados saw some experimentation in VGC, I think? It has a lot of pretty potent speed control options and stuff like Shadow Sneak, Night Shade, Sucker Punch and lol Fel Stinger. It's fragile af but you can always put Sash on it to survive that one hit, just enough to fire off String Shot/Scary Face. Minus two speed for both enemy mons is kinda brutal, chances are that Ariados will be able to fire off one more attack before finally succumbing to whatever.
In practice most of the times it will be double teamed and murdered on the spot... which I suppose is not a bad thing, either?
