@Nidd: That's an interesting point, and while technically correct (And as Bureaucrat #1.0 says, it's the best kind of correct), it doesn't factor in two things:

1. This only applies to Ringleaders 2-4, and only if Ringleader 1 hit enough land.
2. You're much more likely to use more fetchlands before the first Ringleader hits play than after.

So as far as the assertion goes that Fetchlands help your Ringleader draws, for the most part yes they do. But I don't think this makes it worth running the red fetches and subjecting yourself to life loss, risk of Stifle, or the chance of running into some completely random card like Ankh of Mishra or Leonin Arbiter.
