Haunter in GL

I just got a 1449 cp Haunter via a trade and I was wondering about it’s viability in GL. It has SC+Shadow Ball and I have yet to unlock a second move. (I have the resources to)

It’s awesome. You have to use it right but when you get a situation where your opponent has no shields left it can absolutely ball out. It’s only really walled by normal types and dark types which aren’t super common in GL (besides Umbreon). It can’t take a charge move to save its life tho so I wouldn’t use it as a lead, though ive seen people do so.

It’s okay as a lead if you want to take your chances that the opponent is using something really slow like Registeel

But yeah Haunters shadow ball is not to mess around with
