Took the GP list to fnm last night and went 3-1. Played against goblins round one where scooze was an all star and then post board I hit k return, EE, and chalice in the same game so it was pretty lopsided. Played against Green Tron the next round where my opponent went Karn into Karn into Ulamog and still lost. Haste creatures really take the sting out of Karn liberated and getting an Ulamog with obligator is the dream. Game two hit crumble to dust for the win. Round three hit affinity and lost to multiple cranial platings. Round four hit E Tron and we're just faster and more consistent. I like the deck a lot, not sure I want BBE in it at all after testing it.
Changes to the manabases I made was cutting 3 cavern of souls for two wastes and a forest because field of ruin is a real card that exists
You want 13-14 colourless sources to be sure to have one on turn 2, hence 4 groves, 4 karplussan forest, 4 temple and then a handful of other sources like wolf run and mind stone.

This is probably the go to article most people use for constructing manabases. It's worth a read
EDIT: I guess cavern kind of messes up the math a bit on account of being colourless mostly but not when you want to play through counterspells.
