Been playing my Ghost monotype a bit more...
Tauriel
Alice
Goodyear
Loki
Stalfos
Sarlac
Abigail
For those who can count, you can probably notice that I'm currently at a little dilemma...I just caught Mimikyu and I'm a little undecided who to switch out for it...Mimikyu will be a great counter for Dark types (and a good addition in general simply because of it's ability) so I definitely want it on my team....
Misdreavus and Drifblim are putting in work for my team...
Sableye is another good counter for Dark and Ghost types and because of Brick Break it's good against Normal types (which often have dark type moves) (also Sableye is my favourite Ghost type so....he's staying)
Decidueye and Marowak are solid choices for an in-game team (I'm probably going to trade my Marowak over to Sun to teach it Shadow Bone so it can have a good STAB move)
Sandygast is likely on the chopping block, but I do want to at least try out Palossand when it evolves but so far it hasn't really done much for my team...
At this point (if I'm not mistaken) there's only one ghost type left that I can get before post-game...being Dhelmise...
