Éowyn, Fearless Knight

Removal that only fires upward is a rare constraint, and it does clean thematic work here: the exile trigger can only touch a creature with power greater than three, tuning the card as an answer to the thing you actually fear rather than a catch-all. Small blockers walk past it; the oversized finisher that would otherwise end the game gets exiled, permanently, on arrival. Haste keeps the 3/4 body from idling while it waits to matter, and the protection rider is the clever part: rather than protecting Éowyn alone, it hands protection from the exiled creature's colors to every legendary creature you control until end of turn. That reframes a one-for-one into a combat-and-defense pivot in legends-heavy builds, letting your commanders and named heroes swing or block through a color of damage and removal for a turn. The two halves are welded together by the targeting requirement: the protection is defined by "that creature's colors," so it exists only because a legal target existed. On a board of nothing but two-power creatures the trigger has no legal target, cannot go on the stack at all, and you simply resolve a hasty 3/4 with no rider to show for it. The upward-only restriction is what pays for an unconditional exile: it answers the singular large threat and nothing else, a targeted assassin dressed as a midrange creature, built to punish decks that lean on one oversized closer.
