Sorry I didn't notice this comment sooner, I've been out in New Mexico this past week. I certainly agree that evasion/survivability paired with fat is better than twice the fat, but as you noted the deck is powerful anyway, and I was trying to get in touch with what brought me into Magic. Who needs good cards when you have Krosan Groundshaker, Thorn Elemental, Krosan Cloudscraper, and Hundroog? That said, depending on how powerful you want the deck to be, the ideas you've presented certainly can lead to crazy plays, and Sisters of Stone Death could always do with some supplemental Gorgon damage.

You're entirely correct on Troll and lftl; sometimes things just slip through the cracks and both of these cards certainly warrant slots in the deck. I've been thinking about cutting all of the shuffling effects altogether so that the deck can be really relaxing to play, though many of the better ramp spells will be missed, so I'll be adding a lot of cards and have to reevaluate if lftl is good enough sans fetches (i.e. do I have space for cycling lands). Thanks for the feedback.

In a fairly competitive playgroup this might work out, but as Mr Barrel Roll pointed out, it would probably rub most Commander players the wrong way.

Maybe your idea is better after all.
