I use only ghost pokemon for my teams. Competitively, casually, whatever. It MUST have a ghost type in one of the two, or only.
In this manner, I focus on my weaknesses, change strategies, and balance my team all around my favorites.
I recently recruited Froslass to my team and she devastates.
I also like to change a move or two that aren't considered "the best in slot" type of sets for pokemon. Like my Mismagius, people think it's stupid that I have Hyper Voice on her. But it works just fine, because I have modified my team to compliment each other with whatever moves the others have.
Oh, never underestimate a max evasion, substituted Jellicent with Cursed Body. She has taken teams out completely on her own, or stalled people to madness.
