So our area is having it's first con and the organizers asked the video game group at the local university for ideas so they thought of a pokemon league.

We are gonna have fancy badges and everything. I was asked to be an elite four but honestly i don't feel I'm good enough so I decided to be a gym leader.
So I had to pick a type and I chose ghost, Dragon was already taken by the champion guy.
So i need to make a Ghost team.
Im thinking
Gengar
Aegislash
Gourgeist
Jellicent
Spiritomb
Rotom
Froslass

Now we can make the team as big as we want and make the trainers match it.
So 3v3, 4v4 etc.

So I could cut the fat of this team if 6 is a bit too much. I think we have to use the same pokemon each time. so i cant swap pokemon between fights.

Gengar is the only sure thing because of the mega.
Any help would be appreciated.
