Card Details
Mana CostSet
Character Background
Brineborn Cutthroat is a clean tempo threat for blue decks that want to play at instant speed and punish opponents for passing with mana up. The flash body lets it slip onto the battlefield at end step or in response to removal, and every spell you cast on the opponent’s turn grows it into a real clock. In practice, that means it fits best in tempo-control shells packed with counters, cantrips, bounce spells, and cheap interaction—think Opt, Consider, Spell Pierce, and Unsummon-style effects—so you can keep developing while also threatening protection and pressure. Because the Cutthroat only cares about spells during enemy turns, even a single turn cycle can turn it from a modest 2/1 into a game-ending attacker, especially if you chain multiple instants. The Merfolk Pirate flavor also sells the card’s identity perfectly: elusive, opportunistic, and happiest striking when the sea is calm and the opponent feels safe.
