Vault Skyward

Two effects on one card, pointed in whatever direction the board needs, at instant speed. The flying half is the conventional read: grant evasion before blocks are declared so an attacker slips past a ground stall, or hand a finisher the air it needs for one lethal swing. The untap clause is where the card earns its keep. A creature that already attacked snaps back upright to block, manufacturing pseudo-vigilance on a turn it spent tapping out. A tapped creature wriggles free of a sorcery-speed effect that wants it held down. And the two clauses do not have to serve the same plan: flying for the attack with untap setting up the block, or untap purely defensive and the flying an afterthought. That split is what makes the trick more elastic than its rate implies, because it is doing two jobs from one cast rather than one job twice. On an empty table it is close to a dead draw; in a deck that attacks on its own terms and traffics in tapping things down, it quietly buys a second use out of every creature it touches. The untap-as-vigilance reading is the application that has kept this style of trick in print since the earliest combat tricks, holding value even on boards where the flying never matters.
