Lux Cannon

Universal removal that runs on a clock you have to wind yourself. The fantasy is total: this destroys any permanent, no color restriction, no "nonland" or "noncreature" hedge, which puts it in rare company among artifacts that answer absolutely anything. The cost for that breadth is time. It comes down untapped and ready to start charging, but one tap a turn loads a single counter, and three counters spend at once to fire, so the first shot lands no sooner than the turn after you reach three. Every shot after that demands three more turns of patience or external counter acceleration. That asymmetry is the whole design. A removal spell pays its price up front in mana and resolves now; this pays in turns and resolves on a delay, which inverts how you think about it. Instead of holding up an answer for a threat that exists, you are committing to an answer for a threat that will exist by the time the cannon is loaded. Proliferate and other counter-adders short-circuit the wind-up, and that is where the card stops being a slow toy and becomes a repeatable artifact-and-anything destruction engine. Left to its own pace, it is the rare permanent that telegraphs exactly when it will kill something and dares the table to do anything about it in the meantime.
