I've only skimmed the article so far, but wasn't Mike supposed to say whether he supported the Mirrans or the Phyrexians? I guess we can assume Mirrans, since every card he spotlighted except for Flayer Husk was Mirran?
I did a double take when I saw that Kuldotha Red deck that took first place. I think it's a sign that a deck is really really good when a completely standard maindeck can be played in extended to first place.
Even counting the duals most of them are pretty much the same. The ones that aren't are of the typical "pile of rares.dec" variety.
