Any continuous effects with a “for as long as” duration such as that of Awakener Druid ignore phased-out objects.Any one-shot effects that are waiting “until leaves the battlefield,” such as that of Kitesail Freebooter, won't happen when a permanent phases out.Similarly, permanents that phase out with counters phase in with those counters. They will phase in with that permanent and still be attached to it. Each Aura and Equipment attached to a permanent that's phasing out also phases out.An attacking creature that phases out is removed from combat.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. 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.Any creatures that phase in during their controller's untap step will be able to attack and pay a cost of during that turn.−10: Take two extra turns after this one. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)

−3: Target creature you don't control phases out. You may activate loyalty abilities of Teferi, Master of Time on any player's turn any time you could cast an instant. TYPE Legendary Planeswalker - Teferi ABILITY
