I don't really get the appeal of Natural Order. A different colored deck would be able to protect it so much better. BUG or GWU for example. Sure it can be a surprise win, but it's way too clunky. It's 4cmc double green, we only run 8-12 green creatures, and we have no ways to force a resolve or protect Progenitus once it resolves. Our gameplan is disrupt + efficient creatures. NO is SB material at best.
