Rulings
- 2004-10-04 · wotc — Will not affect lands that do not produce mana.
- 2004-10-04 · wotc — Although the color may be altered, any restrictions on the use of the mana are not removed.
- 2008-10-01 · wotc — This has the supertype world. When a world permanent enters, any world permanents that were already on the battlefield are put into their owners' graveyards. This is a state-based action called the "world rule." The new world permanent stays on the battlefield. If two world permanents enter at the same time, they're both put into their owners' graveyards.
- 2016-08-23 · wotc — Any colorless mana that's produced isn't affected.
