General Rulings - 502

• 502.1 - First, all phased-in permanents with phasing that the active player controls phase out, and all phased-out permanents that the active player controlled when they phased out phase in. This all happens simultaneously. This turn-based action doesn't use the stack. See Rule 702.23, "Phasing." [CompRules 2009/07/08]
• 502.2 - Second, the active player determines which permanents he or she controls will untap. Then he or she untaps them all simultaneously. This turn-based action doesn't use the stack. Normally, all of a player's permanents untap, but effects can keep one or more of a player's permanents from untapping. [CompRules 2009/07/08]
• 502.3 - No player receives priority during the untap step, so no spells can be cast or resolve and no abilities can be activated or resolved. Any ability that triggers during this step will be held until the next time a player would receive priority, which is usually during the upkeep step. (See Rule 503, "Upkeep Step.")
