What is your best source of competitive training?

[Rango the Mercenary]

For the first two weeks, I went to GameFAQs, here, Skype, and Facebook to play friends. I usually won most matches with ease. When All is Brawl became Nintendodojo, it reopened the "Ladder" challenge, which is a concentration of some of the best online players there. I have yet to meet a battle there that I have not struggled greatly with. It shows these guys' true skills and I'm almost positive every one of them come from tournament backgrounds.

My area lacks a Smash tournament scene. I'm hoping to change that soon. In the meantime, when it comes to online play, where can I find good challenges with solid, high-level players? I really want to become a top player at Smash.
