Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Well, their Sucker Punches always critted and I had limited super potions, so I couldn't stall them out. They knew Confuse Ray, Hypnosis, Nightmare, and Dream Eater (not all at once, but they knew at least one or two.).
BunBun the Buneary had to solo Morty with only normal moves. Hypnosis always hit, I was Cursed, and I was forced to try about 10 or 15 times to beat him.
BunBun was Careful and knew: Foresight, Quick Attack, Headbutt, and Defense Curl.
