I just got destroyed in Commander (EDH). Worst part of it is that the deck that killed me can do it over and over. It has a guaranteed 4-5 turn win. (EVERY TIME)

It felt a bit broken to me, so I wanted to see if all the cards that were used to destroy me were legal for commander.

But the only site I can find is <http://mtgcommander.net/rules.php>.

Does Wizards let this external site dictate the banned cards for this format?
