You may activate loyalty abilities of Teferi, Master of Time on any player’s turn any time you could cast an instant.
+1: Draw a card, then discard a card.
−3: Target creature you don’t control phases out. (Treat it and anything attached to it as though they don’t exist until its controller’s next turn.)
−10: Take two extra turns after this one.
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.

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.

An attacking creature that phases out is removed from combat.

wotc
Any one-shot effects that are waiting "until [this] leaves the battlefield," such as that of Kitesail Freebooter, won't happen when a permanent phases out.

wotc
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.

wotc
Any creatures that phase in during their controller's untap step will be able to attack and pay a cost of {T} during that turn.

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

wotc
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.

wotc
Phasing out doesn't cause any "leaves the battlefield" abilities to trigger. Similarly, phasing in won't cause any "enters the battlefield" abilities to trigger.

wotc
Teferi's first ability doesn't change how many of his abilities you can activate during each turn.
23-06-2020
wotc
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.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
