Everglove Courier

The pump turns permanent only if you refuse your own untap step, and that refusal is the entire mechanism: the courier sits tapped indefinitely, holding +2/+2 and trample on an Elf until you decide to release it. So the trade is stark. You spend the body of a 2/1 to make an Elf permanently larger, and you do not get that body back unless you let the buff fall away. Most Elf pump from this lineage was instant-speed and disposable, sized to a single combat step. This one asks for commitment instead, treating a creature as a battery you tap once and leave drained. The reward scales with the target rather than the courier, pointing the activation at evasive threats or attack-trigger payoffs instead of vanilla beaters. The arithmetic rarely justified locking a creature out of attacking and blocking just to maintain one +2/+2, so the card stayed a footnote among its tribe: a clever, slightly over-fussy expression of the "stay tapped" mechanic that the Elves around it never needed it to solve.
