2 rulings from Wizards of the Coast
- 1 October 2012Effects that state that the enchanted land doesn’t untap during your untap step won’t apply during another player’s untap step.
- 1 October 2012The enchanted land untaps at the same time as the active player’s permanents. You can’t choose to not untap it at that time.
