I went back for the shuppet and trained it up, don't worry I also trained my dartrix and maxed its speed and attack IVs so I just used pluck and Razor Leaf and one shot the majority of her team, the only challenge was her chatot. I just made it to goldenleaf and got my encounters and now I have a full team, Golett, Drifloon, Duskull and pumpkaboo were my encounters and my Dartrix had evolved a little after the normal gym so my ghost team is set.
