The Jolly Balloon Man

Copying effects usually promise permanence: you make the clone, and it stays until something kills it. This one inverts the deal. Every token it spins off arrives as a 1/1 red Balloon with flying and haste, then dies at the beginning of the next end step, so the copy is a rental, not a purchase. That single-turn lease reroutes the whole exercise away from doubling stats toward doubling triggers. A permanent copy of a value creature is a body; a disposable one that enters and leaves inside a turn is a self-contained package of one enters-the-battlefield event and one leaves-the-battlefield event, front-loaded onto whatever you point the tap at, and repeatable every turn the copier survives. The 4 toughness is the real feature of the frame: it keeps the engine alive through most of the removal and combat aimed at a three-mana body. The haste is not there to swing with the Clown itself (tapping to copy is a sorcery-speed activation, and without vigilance an attack would cost you the click); it exists so the ability is live the moment the creature resolves, no summoning-sick turn wasted. Restricting the activation to your own main phase is the leash on a repeatable copier: no instant-speed blink toolbox, no end-step ambushes, just value the board gets a full rotation to answer. The flavor closes the loop: balloon animals, inflated for a moment and popped by the end of the show. A copy engine reframed as a sacrifice engine, hungry for triggers worth firing twice.
