This deck makes no sense. Why do you need the planeswalkers, or the Fogs? Why play so many subpar slivers like Talon or Quilled Sliver? Not to mention the 20 Ziggurats..

There's an almost immeasurable quantity of decks that are cheaper, more consistent, and LEGAL to play. It's easy to just throw a bunch of broken cards together and just expect them to be an optimal deck. And on top of that, the legal cards you're playing are hardly relevant. Steel Wall? Calling this the "best artifact deck ever" is a HUGE overstatement.
