Aligned Hedron Network
The power-5-or-greater threshold is the whole design: it draws a clean line through a battlefield, scooping the giants and leaving the small stuff untouched. That line cuts both ways, so this is a sweeper you have to build around rather than one you can slam blind. In a deck whose creatures sit safely under the threshold, four mana buys the removal of every opposing finisher while your own board keeps swinging. But the exile is only ever a lease, not a sale: the giants stay gone exactly as long as the artifact stays in play. Crack the Network with any artifact removal and everything it took comes back at once, under its owners' control (not from the graveyard: these are the same permanents, parked to one side and then handed back intact). That turns the effect into a hostage situation more than a board wipe, trading a stack of threats for the obligation to protect an unassuming four-mana rock. Against a deck that respects the line it can decide a game single-handedly; against one carrying the tools to blow up an artifact, it is a delayed liability that returns the whole army the moment the anchor dies. It belongs to the small family of conditional mass-exile effects that hinge on a permanent surviving, and the spread between its best and worst outcomes is wider than most sweepers are ever willing to gamble on.
