Slip On the Ring
A blink spell dressed in Frodo's cloak, and the framing is the point. The flicker itself is old: Cloudshift did the one-mana single-target version, Momentary Blink added flashback, and white has rebuilt the effect many times since. What separates this printing is the second sentence. Where those earlier spells were self-contained (you paid your mana and got your flicker), here the exile-and-return is bundled with a Ring-tempting clause that resolves right alongside it, so casting the card also climbs the Ring's ladder whether or not the blink mattered that turn. The blink half does the usual white work at instant speed: dodge a targeted removal spell by lifting the creature out of the stack's reach, sidestep a combat trick by briefly removing the creature from the equation, or reload an enters-the-battlefield trigger. Because the creature comes back as a new object, it gains summoning sickness on return, so this is protection and value, not a way to sneak in an attacker. The temptation gives the card a second reason to exist: it is a reactive protection instant and a proactive Ring enabler at once, wanted by a deck chasing the escalating Ring effects no matter what gets flickered. The design lesson is how cheaply an evergreen effect gets repurposed by bolting an orthogonal reward onto its resolution: the blink is the familiar half, and the temptation earns the slot in a strategy indifferent to whether the flicker ever mattered.
