502. Turn Structure : Untap Step
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 702.24, «Phasing.»
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.
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 resolve. 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.»)
