Momentary Blink

A flicker spell that does its protective work entirely on the stack: white pays two to exile and immediately return a creature you control, resetting it to a fresh, untapped, summoning-sick body and re-firing whatever enters-the-battlefield trigger it carries. The defensive use lives in the instant-speed window: respond to a targeted removal spell or a kill on the stack, and the creature blinks out from under it, leaving the spell to fizzle when its target vanishes. Because the return happens during resolution rather than leaving the creature stranded in exile, the trick is precise rather than evasive: it answers something already pointed at the creature, not a board wipe the freshly returned body would simply sit through and die to. The real design wrinkle is the flashback into blue. The front half is mono-white, but the graveyard copy demands the spell come back at instant speed in a deck that can produce that blue mana, and that color tax is what keeps the two-for-one fair: a build wanting both blinks has to commit to a second color and accept that the back half costs more and exiles itself afterward. What that buys is two protective or value windows from a single card across two separate turns, turning an ordinary white tempo trick into something a control or value deck can hold and spend twice at the exact moments it matters.
