Part of a cycle of 'filter to colorless' cards in the uncommon slot. These 5 cards were supposed to be mildly worse than a basic land, but gave you a minor activation in exchange. I like what this does to the environment, since this card doesn't set you behind mana or restrict access to a color. It does, however, put more value back into cards with light color requirements, like .

Hmm. The less-irritating half of Sensei's Divining Top. Amusingly combos with Moonring Island and Madblind Mountain.
