Cumulative upkeep [2] (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.) If a land is tapped for mana, it produces colorless mana instead of any other type.  "That which does not bend to the will of Freyalise shall surely break." -Kolbjörn, Elder Druid of the Juniper Order
