Creatures enter tapped.
Whenever chaos ensues, for each opponent, choose up to one target nonland permanent that opponent controls. Untap those permanents. They phase out. They can’t phase in for as long as The Doctor’s Childhood Barn remains face up. When a player planeswalks, those permanents phase in.
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.

A permanent phased out by The Doctor's Childhood Barn phases in during its controller's untap step as normal only if The Doctor's Childhood Barn is no longer face up. (This situation may occur in rare instances if the delayed triggered ability that would normally cause those permanents to phase in immediately is countered.)

Any continuous effects with a "for as long as" duration ignore phased-out objects. Any such effects will expire if their conditions are no longer met after ignoring the phased-out objects.

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.

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

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