Pain Land

Pain lands enter untapped and tap for one colorless mana freely, or for one of two specific colors at the cost of 1 damage to their controller. The Ice Age and Apocalypse cycles are canonical: Adarkar Wastes for white or blue, Llanowar Wastes for black or green, and Battlefield Forge for red or white. The damage is dealt by the land itself on each colored tap, which distinguishes them from land_types.shock_land, where 2 life is paid only once on entry rather than per activation. Also distinct from any-color self-damaging lands, which sit in land_types.utility_land since they tap for any color rather than two specific ones.
