Maëlig I like your list, but I have what I see would be a couple "upgrades". If you're going to play wasteland, Crucible seems like it's a must include to be able to recur wastelands in order to deal with Cavern of Souls and other problematic lands. Then you could cut a Tundra for an Academy Ruins. I'd go something like -1 Tundra, -1 Snapcaster, -1 E.Tutor, -1 E.E., -1 Counterspell for +1 Academy Ruins +1 Crucible of Worlds, +3 Ponder.
