Following the rule that abilities can only resolve while they are in play, Brad Andres clarified that when a Dust Imp (upgraded with a Biomatrix Backup) is destroyed, it could resolve in two ways, with the order being chosen by the active player. If the Dust Imp's Destroyed: ability is resolved first, its controller would gain 2 Æmber, and then the card would be moved to the owner's archive. If the Destroyed: ability of Biomatrix Backup is resolved first, then the Dust Imp is placed in its owner's archive, from which Dust Imp's Destroyed: ability cannot resolve, as it it no longer in play.
