Name: Immunity Abuser
Description: A fairly bulky pokemon that, through its typing and ability, would have the maximum amount of immunities possible.
Explanation: Yeah, the first thing that comes to mind is Spiritomb, but thats not what I'm suggesting. Spiritomb has no weaknesses, I'm going for something will a bunch of immunities. No pokemon really has the maximum immunities, and those that do aren't super bulky (Gengar and Mismagius). For example, Ghost/Steel with Levitate.
Doesn't that kind of imply a typing?
