The version i'm thinking about has some more lands, 4 dakmor + 4 paradise + 2 "free slots" (It could be petrified field, riftstone portal, wasteland and strip mine...) And 4 Diamonds.
As I said, it's more combo focused, but It has 2 FoV, though It could be 4 (i'm afraid not having enough green cards)
In the fatesticher version, LED it's the best card you can draw, apart of bazaar. It lets you dredge from t1, and unearth fatesticher. That's a 95% chance of T1 win. I don't know why you would play any other rock over it.
With London mulligan, I'm thinking in play full set of mox diamond and dakmor savage, in addition to the 4 mana rocks (Lotus, LED, shapphire and petal). Obviously it's even a more combo version, with less interaction.
