Fantastic article on a very relevant metagame issue.

I actually like Vincent’s list as compared to Ben Steiner’s list from Legacy Champs (also played by Johnathan Mosier, below). It gives up some consistency without Ponder (and some ability to find Natural Order), but it should have an easier time finding three-cost spells for Counterbalance, and the extra Trygon Predators and fourth War Monk seem like good metagame calls (and extra Green creatures are always useful with Natural Order). Vincent is also splashing Red for sideboard cards.
When I first saw Vincent's list, I was very excited at how he managed to fit all the cards I wanted in my UGW NO/CB list into his. Despite top-eighting at Legacy Champs with my list, I was ready to give mine up for his. But when I put his list into MWS and tried it, there were a few problems.

First of all, his list is 61 cards. I'm a firm believer that there is no 61 card list that can't be improved by cutting one card, and I'd like to see anyone provide a counterexample.

Second, I've found basic Plains to be weak in this kind of deck. You only run eight white cards, and none of them cost more than one white mana. You can also get white mana from Noble Hierarch off a basic Forest.

Third, Volcanic Islands in the main really suck. When you're trying to get for Rhox War Monk, and for Natural Order, Volcanic Islands are a pain in the ass. In most games, they're like basic Islands that are vulnerable to Wasteland, which is unacceptable. When I experimented with Firespout, I tried running two Volcanic Islands in my sideboard, but the package took up too many slots, and would often lead to me over-boarding. I also experimented with Dark Confidant, and trying to get black for him as well as white, blue, and green, was too difficult.

tl;dr --- If you run Natural Order and Rhox War Monk, there's no room for a fourth color, no matter how light the splash.

I've made a lot of changes to my list since Legacy Champs, and many of the changes came from my experimentation with his list. I agree that his list looks better than mine on paper; initially, even I thought as much. But when I played with it, it didn't work as well as mine.

Here's what I'm currently using, with good success:

4 Tropical Island
3 Tundra
4 Misty Rainforest
4 Windswept Heath
1 Flooded Strand
1 Forest
1 Island
1 Dryad Arbor

4 Noble Hierarch
4 Tarmogoyf
4 Rhox War Monk
2 Trygon Predator

4 Force of Will
3 Daze
4 Brainstorm
4 Sensei's Divining Top
4 Counterbalance
4 Swords to Plowshares

3 Natural Order
1 Progenitus

SB:

1 Trygon Predator
2 Relic of Progenitus
1 Tormod's Crypt
2 Propaganda
2 Ghostly Prison
4 Spell Pierce
3 Engineered Explosives
