Counterspellremoval$0.98The classic straight upgrade to Cancel: it counters any spell for just two mana, making it the most efficient unconditional permission spell in blue.
Dissipateremoval$0.56Very close to Cancel in cost and function, but exiles the countered spell instead of sending it to the graveyard, which can matter against recursion.
Essence ScatterremovalBudget$0.05A cheaper counterspell that fills a similar defensive role, though it is narrower because it only hits creature spells.
Negateremoval$0.54Another common 2-mana permission spell that protects you from noncreature threats; it is narrower than Cancel but often more efficient in practice.
Sinister Sabotagecard_draw$0.13A functional cousin to Cancel with the same mana cost, adding surveil to improve card quality while keeping unconditional counter coverage.
Excludecard_draw$0.13Similar midrange countermagic that replaces itself by drawing a card, but only counters creature spells.
No More Liesremoval$4.16A modern three-mana unconditional counterspell in white-blue that plays a very similar role, with upside from exile against troublesome cards.
Arcane Denialcard_draw$2.53A budget-friendly counterspell that can hit any spell and replaces itself, though it gives the opponent extra cards later.
