Vronos, Masked Inquisitor

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.

Vronos, Masked Inquisitor's last ability doesn't remove any abilities the target artifact has.

Effects that modify a creature's power and/or toughness, such as the one created by Giant Growth or a +1/+1 counter, will apply to the creature no matter when they started to take effect.

Permanents phase back in during their controller's untap step, immediately before that player untaps their permanents. Creatures that phase in this way are able to attack and pay a cost of {T} during that turn. If a permanent had counters on it when it phased out, it will have those counters when it phases back in.

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

Phased-out permanents are treated as though they don't exist. They can't be the target of spells or abilities, their static abilities have no effect on the game, their triggered abilities can't trigger, they can't attack or block, and so on.

Any continuous effects with a "for as long as" duration, such as that of Extraction Specialist, ignore phased-out objects. If ignoring those objects causes the effect's conditions to no longer be met, the duration will expire.

The resulting artifact creature will be able to attack on your turn if it's been under your control continuously since the turn began. It doesn't matter how long it's been a creature, just how long it's been on the battlefield.
