Hallowed Moonlight

The genius of this design is in the word "cast." A reanimation spell, a token generator, a blink effect, a Show and Tell, anything that puts a creature onto the battlefield without it being cast as a spell: all of it gets exiled until end of turn instead. The line excludes the obvious cheats while leaving hardcast threats untouched, so it reads as a scalpel for a specific class of put-it-into-play strategies rather than a catch-all. Precision matters here, and it is precision of a particular kind: this is a continuous replacement effect, not a spell that points at anything, so it does nothing to creatures already on the battlefield, and it leaves cascade and evoke alone because both still instruct the player to cast the spell. The hatebear-in-an-instant has a long lineage. Containment Priest does similar work on a body and stays around for the long game; Torpor Orb attacks the enters-the-battlefield trigger rather than the entry itself. What separates this answer from that family is the cantrip stapled on. Most narrow hate sits dead when the matchup never shows up; this one replaces itself, so the cost of guessing wrong is two mana and a fresh draw rather than a blank in hand. Instant speed is the other load-bearing piece: hold it, let the opponent commit to the reanimation or the token swarm, and answer at the moment the value would land, then refill.
