I played The Mountains Win Again in the Vintage master RThomas won, and I piloted the deck to 10th place at 4-1-1 due to an ill-advised draw in round 6, despite me being a T1 newbie. This is the deck I played:

1 Plains
4 Plateau
2 Wooded Foothills
2 Flooded Strand

4 Grim Lavamancer
1 Genju of the Spires
// Spells
4 Swords to Plowshares

I beat Affinity, Ichorid, and Workshop Aggro, and TMWA's greatest asset is the immense amount of hate. I didn't play Jotun Grunt because I didn't know how to fit in in, and I didn't have the foresight to play Hide instead of Dis-E. Ironically, I found myself fetching for a basic mountain and a basic plains first due to wasteland fear. Pyrostatic Pillar and Genju weren't hot for me, and I don't get the random 1 of Null Rod and Sacred Ground. The only things I don't like about the deck is that it has no way to generate card advantage, it relies on winning attrition wars. Also, the deck doesn't get raped by Kataki or Flux. I like Goblin Welder as a defensive measure because you can weld out an offensive artifact with a mox, and then kill the mox again. T1T beat me with Darksteel Colossus both times because I wasn't playing Hide and I couldn't get STP or Welder out.
