Basics (generally forest + island + wastes) is 15, Eye of Ugin is 16, 4 fetches and duels, 24. Then you've gotta consider Tabernacle, Bojuka Bog and Glacial Chasm, in addition to Sea-Gate Wreckage and Thespian's Stage, all utility lands that can see play in the main or the side.
I just don't see what Wasteland does for us. We have no clock to support it, and there's really not any lands aside from Inkmoth Nexus that I can really see being a problem. Plus, I want to land Needle on Wasteland like 90% of the time, so I'm killing my own card in that scenario.
Eldrazi Temple generates less mana than my other lands, frankly. It doesn't do anything to help accelerate a Titan or any spell other than Thought-Knot Seer (which is a sideboard card in a lot of builds), and really doesn't help all that much for the big Eldrazi comparatively. I'd rather have the utility of a Sea-Gate Wreckage or a Thespian's Stage than the edge cases where a temple does anything for me, frankly.
