I forgot Spiritomb existed and he may better, everyone never expects Gengar to have Curse...
Right yeah sorry about that. Spiritomb soley because it has better defensive capability which Gengar just doesn't. I actually like curse on a moveset It'd be nice to see it work properly. It has decent support options aswell with rest or you could just as easily use leftovers.
It's so rare to see Spiritomb used by anyone who doesn't hack it's ability.
Main problem is that the team is incredibly frail for a stall team. Gengar, Smeargle, Dugtrio and even Whimsicott will very rarely manage to switch in without taking crippling damage. None of them have recovery either, so any attempts to stall will be very short lived. Curse doesn't really work (IIRC, unless it has changed) on Ghost types, since the opponent can simply switch out and leave you with less than half health.
Without wanting to sound cruel, I'd say start again, since the team needs a huge overhaul to be successful at stall. Have a read of this to get you started:
