Thorn of AmethysttaxBudget$1.16Very close tax effect that increases the cost of noncreature spells by {1}, functioning as a classic sphere-style prison piece. It is especially similar in decks that want to slow combo and control.Vryn WingmaretaxBudget$0.24Imposes a {1} tax on noncreature spells much like Sphere of Resistance, but on a creature body. It fills the same disruptive role while being easier to recur or tutor in creature-based decks.GlowridertaxBudget$1.34A creature version of the same general effect, making noncreature spells cost {1} more. It is a functional analogue for white prison and tax strategies.Thalia, Guardian of ThrabentaxBudget$0.39Taxes noncreature spells by {1}, often serving the same purpose of slowing down cheap interaction and combo. It is one of the most efficient white disruption pieces in the format.Chalice of the VoidtaxBudget$13.29While not a blanket tax, it serves a similar anti-cheap-spells prison role by shutting off spells of chosen mana values. It is a staple lock piece in many of the same decks that want Sphere of Resistance.Trinispheretax$20.15Another classic artifact prison card that makes spells cost at least {3}, often functioning as an even stronger version of Sphere in tax-heavy decks. It is usually more punishing but less symmetric in practice against low-cost spells.Defense GridtaxBudget$8.84Not a universal tax, but it protects you by making spells cast during opponents' turns cost {3} more. It fills a similar role in slowing interaction and forcing through your game plan.God-Pharaoh's StatuetaxBudget$0.78A much slower but heavier tax effect that makes opponents' spells cost {2} more and pings them each turn. It occupies the same disruptive artifact slot in prison and ramp decks.
