  Each Aura and Equipment attached to a permanent that’s phasing out also phases out. They will phase in with that permanent and still be attached to it. Similarly, permanents that phase out with counters phase in with those counters.

  Choices made for permanents as they entered the battlefield are remembered when they phase in.

  If an opponent gains control of your creature and it phases out and the duration of the control-change effect expires before it phases in, that permanent phases in under your control as that opponent’s next untap step begins. If they leave the game before their next untap step, it phases in as the next untap step begins after their turn would have begun.

  While a permanent is phased out, it’s treated as though it doesn’t exist. It can’t be the target of spells or abilities, its static abilities have no effect on the game, its triggered abilities can’t trigger, it can’t attack or block, and so on.

  You draw a card and discard a card all while Teferi’s first loyalty ability is resolving. Nothing can happen between the two, and no player may choose to take actions.

  An attacking creature that phases out is removed from combat.
• 2020-06-23
  Any continuous effects with a “for as long as” duration such as that of Awakener Druid ignore phased-out objects. Any such effects will expire if their conditions are no longer met after ignoring the phased-out objects.
