Authority of the Consulsutility$5.37Slows opposing creatures by making them enter tapped, similar to Kismet’s tempo-denial plan. It also gains you life, giving it extra value in white stax shells.
Blind Obedienceutility$5.34Extort makes it a flexible tax piece, and it still causes opponents’ artifacts and creatures to enter tapped. It’s a closer, more efficient cousin to Kismet in many decks.
Meekstoneutility$10.08A classic white stax piece that restricts combat by keeping larger creatures from untapping fully. It serves a similar board-slowing role, though it works differently from enter-tapped effects.
Frozen Aetherutility$1.45This is one of the closest functional analogs to Kismet, making opponents’ permanents enter tapped. It hits the same broad stax/tempo role while adding no extra color requirements.
Imposing Sovereignutility$0.42It taxes opposing creatures by making them enter tapped, functioning as a lower-cost creature-only version of Kismet. Best in aggressive white decks that want to keep blockers off the board.
Thalia, Heretic Catharutility$2.21A creature-based tempo piece that makes nonbasic lands and creatures your opponents control enter tapped. It overlaps heavily with Kismet’s plan against mana bases and combat development.
Loxodon Gatekeeperutility$1.85A creature version of the enter-tapped effect that also hits artifacts, lands, and creatures. It is very close in function to Kismet, especially in prison-style decks.
Urza's Sagautility$36.94This is not a direct tax effect, but it can tutor mana rocks and prison pieces that support the same slow-the-game plan. It is a stronger value engine in white-based artifact prison shells.
