Null Rodstax_hate$119.76This is the closest functional analog to Stony Silence, shutting off activated abilities of artifacts on a permanent basis. It is colorless, making it playable in more decks while filling the same hate role.
Collector Ouphestax_hate$3.97It also prevents artifact activated abilities from being used, serving as a creature-based version of the same hate effect. The creature type makes it more vulnerable, but it can be tutored and recurred more easily in green decks.
Karn, the Great Creatorstax_hate$13.20While broader in scope, it shuts off opposing artifact mana rocks and activated artifact lines by turning them off in practice. It is a higher-cost, more flexible hate piece that can also fetch sideboard silver bullets.
Energy Fluxstax_hateBudget$0.34This punishes artifact-heavy decks and can effectively suppress artifact activations by making artifacts difficult to keep on the battlefield. It fills a similar anti-artifact prison role, though through upkeep tax rather than a hard lock.
Cursed Totemstax_hate$7.51It stops activated abilities of creatures rather than artifacts, but it occupies the same 'shut off activated abilities' hate slot in stax decks. If you're looking for a comparable lock piece, this is a common parallel effect.
Phyrexian Revokerstax_hateBudget$0.33It can name a problematic artifact and disable its activated abilities, giving you a targeted version of the same disruptive plan. It is more surgical than Stony Silence but fits artifact-hate shells well.
Sorcerous Spyglassstax_hateBudget$0.30Like Revoker, it answers activated abilities on specific artifacts by naming them before they can be used. It is more flexible because it also checks hands, though it only hits one permanent at a time.
Damping Spherestax_hate$1.08It is not a direct artifact-ability shutoff, but it plays a similar disruptive role against artifact-based ramp and combo by taxing explosive mana development. It is a common sideboard alternative when the goal is to slow artifact-driven decks.
