ETB tapped, nonbasic, colorless only. There's a lot of competition for spell slots, since I don't think you can rightly consider this a land slot.
very true.
any man-land is just better.
in a non-proxy tourney i usually put a land like this in place of a mox, which i wont do since it etb tapped

i mean colorless mana is enough of a draw back why did they have to add etbt instead of ,lets say, making it Legendary?
