@DB: I might have some suggestions for you, but I would need to see what else you're using, first.
Heh, you name it, I'll find it. =P
@DB: Well, I wouldn't really call Blissey a Tank. I would definitely call it the best Special Wall of any Pokemon, period, but not necessarily a Tank. Its Special Attack isn't strong enough to warrant a Tank. A BoltBeam combo or Seismic Toss can really throw a lot of Pokemon of guard, but it wouldn't warrant a Tank.
Tank was the first thing that came to mind; I really have no idea what to call it. =P
Trying to find a good Pichu to send over, ATM. Although I may have to deal with a neutral nature at this rate... >_<
