Hmm, well, to be completely honest I don't know how it can be accomplished too, and I think I said that somewhere in my post. Maybe the correct way to do this is just try to change the basic speeds that people aim for, like you said, so I might just try to edit my post. If what I underlined in my concept can't be done, I might just change it a bit. What's your opinion?
Either that or I can just give up on the idea. In my opinion, I think that if CAP10 makes the metagame shift in it's common speed tiers, we might find out a specific style of play that is best suited to such times. This might help when the metagame is changed, i.e. new Pokemon become OU. This information is also sure to help when Gen 5 comes around. Maybe I can change the concept to "a Pokemon that destabilizes the metagame speed-wise". I'm sure we can learn about the metagame when/if that happens.
Maybe something like auto Trickroom? I mean Trickroom can already throw a whole game out of whack, imagine a turn one Trickroom (that lasts 2-3 turns?). I'm not saying I necessarily like the idea of a walking Trickroom, but it's certainly one way to accomplish this goal. If such a CAP became popular enough fewer people would aim for the higher speed tiers, or keep at least one Pokemon with horrendous speed to "counter" it.
