I'm trying to help a friend construct an Ulamog EDH deck and we need a good amount of cheap lands or artifacts to produce a good amount of colorless mana, does anyone have any suggestions?
If it's casual just let him use basics
{Bant Panorama} and friends, {Myriad Landscape}, {Krosan Verge}...
There's lots of colorless lands under a dollar - they're just not that great.
