Phasing

Phasing is a static ability from the Mirage block. It works at each player's turn during the untap step.

Before the player untaps his or her permanents, simultaneously all permanents that player controls with phasing phase out and all permanents phased out phase in. If the player skips his or her untap step, the phasing doesn't occur. To "phase out" means to be moved from play to the phased-out zone. To "phase in" refers to be moved from the phased-out zone to play.

A permanent that phases out and phases in again is considered the same permanent, regardless of the rule that says that a permanent is considered differently when it leaves a zone. A spell or ability that targets a permanent won't have an illegal target if the target permanent phases out and in before the spell or ability resolves, because it's treated as the same permanent. Effects with limited duration and delayed triggered abilities can't affect a permanent if it phases out. However, continous effects will still work in the permanent if it phases out.

When a permanent phases in again, it stays with all the counters it had, remembers the choices made from it, the player who controlled it, the opponents it has damaged, etc.

Auras, Equipment and Fortifications attached to a permanent that phases out phase out along with it. This form of phasing out is known as "phasing out indirectly". If an Aura phases in, but it's now illegally attached to the permanent, it returns to play and then is put into its owner's graveyard. If a now illegally attached Equipment or Fortification phases in, it returns to play and then remains in play unttached. Both are state-based effects.

A creature that phases in can attack and play activated abilities with the symbol as though it had haste. This applies even if the creature phases out and in the same turn it came play. (See summoning sickness)
