Quicksilver Gargantuan

Clone effects normally inherit their target's stats wholesale: that is the deal Clone struck, and most copy spells since have followed it. This one breaks the inheritance on exactly one axis. You take every ability, every keyword, every printed name of the creature you copy, but the body is locked at 7/7 no matter what you point it at. The design logic is straightforward once you see it: a copy effect's power is bounded by the best creature on the battlefield, so anchoring the stats to a fixed, generous number means the card stops scaling with the biggest thing in the room and instead pays a flat premium for it. Copying a small utility creature gives you a 7/7 with that creature's text, which is the upside; copying a genuine giant means surrendering its size for a number that is merely large, which is the cost. At seven mana it is the expensive end of the clone family, and the fixed body is what it buys instead of the usual mana discount. The result is a copy spell that cares less about matching a finisher's footprint than about laundering an ability onto a reliably threatening frame, which makes it sharpest when the abilities you want are attached to bodies you would never field at full size otherwise.
