Underground River (7ED-350) is a rare Land from Seventh Edition that can produce colorless mana or hybrid blue/black with a life-loss drawback. It taps for either {C} or taps for {U} or {B} but deals 1 damage to you when producing colored mana. Its color identity is both blue and black, making it useful in two-color decks that can tolerate the small life penalty.
