Winter Orbstax$13.56It attacks untapping in a similarly oppressive way, limiting how much mana players can effectively access each turn. It is one of the classic resource-denial pieces that pairs with creatures or tap effects.
Static Orbstax$5.28Like Smoke, it restricts untapping and slows the board down significantly. It is broader than Smoke because it limits all permanents rather than just creatures.
Tangle Wirestax$31.25This is a tempo-denial piece that similarly constrains what opponents can untap or use each turn. It creates a short-term lock that often functions as a comparable disruption tool in resource-denial decks.
Meekstonestax$10.08It limits how aggressively creatures can function by keeping larger threats from untapping, which plays a similar board-stall role. While narrower than Smoke, it is a strong budget-style stax option.
KismetstaxBudget$0.55It slows opposing permanents by making them enter tapped, which complements the same kind of tempo denial Smoke provides. It is broader in scope but fills a similar control/stax role.
Blind Obediencestax$5.34It taxes opponents' artifacts and creatures by making them enter tapped, reducing their ability to pressure you immediately. This is a softer but more flexible analog to Smoke's combat suppression.
Authority of the Consulsstax$5.37It is a cheap way to slow creature decks by making opposing creatures enter tapped and gain life. While not an untap restriction, it serves a similar anti-aggression role.
Crawlspacestax$7.78It limits the number of creatures that can attack, which functions as another combat-dampening prison piece. Compared to Smoke, it protects you by constraining board pressure rather than untapping.
