Don't Blink

Exile has quietly become one of the game's busiest resource zones: blink effects that flicker a creature back through exile, the whole family of "cast this from exile" engines, and reanimation-from-exile riffs that dodge graveyard hate by staging threats somewhere else entirely. This answers that entire axis with one instant, redirecting any creature that would enter from exile or arrive after being cast from exile straight back into its owner's library, shuffled rather than merely bounced. The shuffle is the sharp part: a returned creature does not land on a knowable top of deck or in hand where it can be replayed, it vanishes into randomized depth, which turns a tutored-and-staged threat into a coin flip. Because the effect is a floor that lasts until end of turn rather than a single targeted redirect, it catches multiples, blink loops that would otherwise trigger repeatedly, and staggered exile-then-cast sequences in the same window. The tension is that the answer is worthless against creatures cast normally or entering from hand; it does nothing to a hardcast threat, which is exactly why it carries cycling. When the opponent is not doing the specific thing this punishes, the discard turns it into a fresh card rather than a dead hold, so the floor on a hyper-narrow answer is a cantrip rather than a blank. It is a hoser built for a mechanic, not a color, with a release valve stapled on so it never fully bricks a hand.
