Hi, I'm new to the forums. Used to play Magic from Beta to Mercadian Masques. Very happy to see there's a way to keep playing with the new cards without having to spend a fortune on them!
Anyway, I was stuck on this challenge for a long time. Lots of unlucky draws and game crashes (especially when trying charbelcher decks). I eventually settled on the following control build that made the challenge absurdly easy! Can't believe I didn't figure it out earlier.
12x Island
4x Tundra
4x Underground Sea
1x Mox Emerald
1x Mox Jet
1x Mox Pearl
1x Mox Ruby
1x Mox Sapphire
1x Sol Ring
1x Black Lotus
4x Tangle Wire (easy enough to unlock it in March of the Machines 1)
4x Vedalken Shackles
4x Meekstone
4x Thopter Foundry
4x Sword of the Meek
4x Ichor Wellspring
4x Mycosynth Wellspring
3x Smokestack
2x Mortarpod
The deck is designed around control and synergy, and you get more and more options while your opponent keeps getting less. In the beginning, use Tangle Wire, Meekstone, Mortarpod and Vedalken Shackles to shut down the opponent. Use the Wellsprings to gain card (to draw into combo) and land (for the Shackles) advantage. Drop a Smokestack as soon as possible. You can sacrifice Wellsprings, Mortarpods, 'empty' Tangle Wires, surplus Meekstones and land to it. Keeping them between 1 and 3 counters should usually do the trick. Keep in mind you can tap most of your artifacts to Tangle Wire and they'll still work, except the mana ones and the Vedalken Shackles.
The Thopter Foundry/Sword of the Meek combo gives you blockers, attackers, Smokestack fuel and lifegain (very important against the burn deck!). The Thopter Foundry is the important part of the engine, as you can also sacrifice the Wellsprings, Tangle Wires and surplus artifacts (Moxes, Meekstones). You can use it to get rid of a redundant Smokestack as well. If direct damage is needed, you can ping creatures and players by equipping the Mortarpods to the thopter tokens.
Mulligan until you get a hand that either has the combo or plenty of control options. If you have a Mycosynth Wellspring you can afford to keep a low land hand. I used the Shackles mostly defensively. You'll have enough islands to grab their best creature every turn.
The burn deck is the only difficult match-up. Keep it locked down with Tangle Wire and Smokestack and make sure you get a Thopter Foundry for the life gain! The rest of the decks should be easy. You'll be assisted a bit by crappy computer AI. It never seems to Disenchant/Naturalize the Thopter Foundries, but wastes them on the tokens or Sword of the Meek. The mirror match is laughable, since the AI immediately sacrifices the Thopter Foundry to itself.
Hope this deck/guide helps people out. I was getting very frustrated until I built this.
