Uh, ok, people seem to actually want to talk about this. Super cool.
The original idea was conceived when my friend said that we should make a Smogon legal team with the goal of losing the battle. NFEs weren't allowed, but I'm removing this rule now that the original idea is gone. The "Shit Tier" is basically Pokemon that aren't even useable in NU or RU or whatever the (benevolent?) overlords at Smogon want to call it. In order for this to work I think it's best to also suggest NFEs that could be added. Due to the low number of Pokemon that seem to be allowed I think it's best to just keep the allowed list rather than make a ban list.
Procedure for getting a Pokemon added:
Suggest it and it will be put up for review.
Procedure for getting a Pokemon on the list banned:
As was stated, this was a project started be me and my friend. What that means is that he made the list and tried to get one of every type on it. Something being overpowered and in need of being banned is completely reasonable.
To get this done post a set that would over power the rest of the "tier". If it is determined that nothing can actually counter this set or that very few Pokemon can counter it then the Pokemon in question will be banned.
Procedure for being added to the review board:
So if you really care enough about this and want to help with it, just ask. I'm thinking a board of seven will be good. This would include myself and possibly steelfire81, who made the original list and had the idea.
If you want to be on the board then all you really have to do is ask. No special application is necessary, the board will review your posts and stuff and decide if we think you are versed enough in competitive battling to be on the board. What could go wrong with a self regulating governing body?
