Rule of LawstaxBudget$0.44The closest functional analogue, locking each player to one spell per turn with the same mana value and effect profile.
Eidolon of RhetoricstaxBudget$0.44Essentially the creature version of Arcane Laboratory, applying the same one-spell-per-turn restriction while adding a body.
Deafening Silencestax$0.87A cheaper tax piece that similarly limits spell-heavy turns, though it only stops noncreature spell chains.
Archon of Emeriastax$2.67A broader hate piece that restricts spell sequencing and mana bases, overlapping with Arcane Laboratory's anti-combo role.
Curse of ExhaustionstaxBudget$0.40This enchantment creates a similar one-spell-per-turn lock on a chosen player, serving the same anti-combo/stax function.
Lavinia, Azorius RenegadestaxBudget$0.47Not identical, but it functions as a low-cost control piece that disrupts fast or free-spell combo turns in a similar anti-explosive-spell role.
Dovin, Hand of ControlstaxBudget$0.25A tax effect that slows opponents' spell deployment and artifacts, fitting the same control/stax shell even though it is not a hard one-spell lock.
Trinispherestax$20.15Another classic anti-combo prison card that limits spell efficiency and punishes storm-style turns, overlapping in function as a lock piece.
