Mercurial Pretender

Most clone creatures are one-shot replacements: a copy goes onto the battlefield, the original effect resolves, and the body is just a body from then on. The bounce ability rewrites that arithmetic. By giving itself a way back to hand for a fixed cost, this Shapeshifter turns a single clone into a reusable enters-the-battlefield engine: copy your best value creature, get the trigger, bounce it back, and do it again next turn when the mana is free. That self-recursion is the whole design idea, and it inverts the usual clone tension. Where a printing like Clone or Phantasmal Image asks you to choose the best target on the board right now and commit to it, this one is built for repetition, mining the same enter trigger over and over rather than capitalizing once. The cost is paid in the body. As a copy it inherits the original's stats, so it is as durable as whatever it imitates, but the bounce keeps it from ever becoming a stable board presence: returning it to hand resets the loop and surrenders the position. It is a clone built less to win the board than to keep harvesting the same effect, which makes the creature it copies the real decision, not the copy itself.
