Rebuking Ceremony
Tempo, not removal, is the trick to reading this one. Putting two artifacts on top of their owners' libraries destroys nothing: it costs the controllers their next two draws to replay what they already had, never touching the graveyard or any other axis on the battlefield. The targeting flexibility is the pitch, since it hits any two artifacts regardless of who controls them, including your own when you want to recur a pair of enters-the-battlefield triggers. The catch is the price. Five mana at sorcery speed for a setback the opponent partially undoes over the following two turns is a steep rate for an effect that produces no permanent advantage, which is why green's traditional artifact answers have leaned on outright destruction (Naturalize and its descendants) rather than this softer reset. What keeps Rebuking Ceremony from being purely a curio is the library-stacking line: against a deck that has already committed two key artifacts, locking the next two draws into known, redundant cards can buy a full turn of breathing room while green develops its board. It is artifact hate that departs from green's idiom, choosing to stall the engine rather than break it.
