Rulings are collected from many sources. See credits and disclaimer at the end of the file for details. Both of these editions use the same rules.
Complete text is included for cards from all expansions.
These rulings are updated monthly. For example, if both this and Recycle are in play, the most recent in play decides your hand size. That creature becomes an artifact in addition to its types. Untap a tapped land an opponent controls. If you do, add one mana of any type that land could produce to your mana pool.
