Hydroblastremoval$2.77A classic blue answer to red spells and red permanents, often even more efficient than Douse against the same color. It is highly color-restrictive but fulfills the same anti-red interaction role.
Blue Elemental Blastremoval$4.37Directly counters a red spell or destroys a red permanent, making it one of the closest functional equivalents. It serves the same anti-red sideboard role with a lower upfront cost.
Spell Pierceremoval$0.29A cheap blue soft counter that can protect you against many early plays, including red spells if the opponent can't pay the tax. It is less color-specific, but it fills a similar counterspell role at a lower rate.
Negateremoval$0.54A simple, efficient blue counterspell for noncreature spells. It does not target only red spells, but it occupies the same general slot of cheap countermagic.
Essence ScatterremovalBudget$0.05Another low-cost blue counterspell, this time aimed at creature spells rather than red spells specifically. It is a functional alternative if the goal is cheap reactive blue interaction.
Counterspellremoval$0.98The most iconic unconditional blue counterspell, offering broader coverage than Douse. It is the premier strict upgrade in terms of raw flexibility, though it lacks the anti-red specificity.
Arcane Denialremoval$2.53A versatile 2-mana counterspell that can answer any spell, including red ones. It trades card advantage for flexibility and fits the same general interactive slot.
Mana Leakremoval$0.45A strong early-game blue counter that can often stop the same red spells Douse would target. It is more flexible but weaker later unless the opponent can pay.
