Wow! The ones I have left are really hard... well except maybe Sliver Nation, I still haven't even checked what that is, yet. Anyway, this is my deck that beat
March of the Machines #2. I should emphasize that this took many, many, many tries, and I tweaked all kinds of things in this deck, so don't expect to make it the first time around with this!

WeakstoneOther cards I tried were
Sphere of Resistance,
Ankh of Mishra,
Ivory Tower,
Howling Mine,
Serum Powder, and
Ensnaring Bridge.
Using a vise deck seemed the most obvious way to go, so I started with that. It eventually became Vise/Stax in order to add removal stuff, and then I added scrolls and belchers for more damage sources.
Tangle Wire is sick with
Meekstone and
Winter Orb. Tap your own vises, tangle wires, stacks, and zuran orb first, since they still work tapped. After that, tap anything you aren't using, like maybe a cursed scroll or meekstone you don't need that turn. The
Smokestack generally ate
Mana Vault/Crypt first, then any extra meekstones, winter orbs, or lands. (always land before moxes due to winter orb)
The deck is actually quite hard to play, and in general I found through experimenting that you rarely want to put more than 1 counter on your smokestack. You can normally afford the loss of one card a turn, maybe 2 for a short time, but at first I was loading the darn thing up every turn, and that didn't work. I'm not sure how to explain it, except that if you play a few dozen times with it, you'll see :p
