So guys what do you think are pokemon that are insanely good inside a Nuzlocke?
Isn't Ralts really rare in all of the places he's obtainable though? I would say that knocks Gardevoir down a rung or two in usefulness, just by virtue of the fact that probability isn't in your favor when it comes to catching one. Although, it's not like it doesn't happen - in my current Emerald Nuzlocke, my Pokemon for Petalburg Woods was Slakoth, and he's pretty damn rare.
As for Pokes that rape the game... I don't know about late game, but in HG/SS, Geodude absolutely wrecks the first few gyms. You always hear horror stories about Whitney, but Geodude totally laughs in her face. If you're playing the old games, he's even pretty good against Morty since his Ghosts don't have Levitate and you can abuse Magnitude.
