Blubbernder Schlamm

Hexerei, B (1)
Immer wenn bis zum Ende des Zuges ein Spieler einen Sumpf für Mana tappt, produziert dieser ein zusätzliches B.
Der Schlamm fordert hundert lebendige Dinge, bevor er auch nur einen seiner mageren Schätze preisgibt.
Illus. Greg & Tim Hildebrandt

Sorcery
Until end of turn, whenever a player taps a Swamp for mana, that player adds {B} to his or her mana pool (in addition to the mana the land produces).¹

Gatherer Card Rulings [Nov 2009]

• 10/4/2004: Affects lands with type Swamp, not lands that are named "Swamp."
• 10/4/2004: Affects lands tapped for rest of turn, not just swamps on the battlefield at the time it resolves. This is because it affects players and not the lands themselves.
