HurricaneremovalBudget$0.49This is the closest functional match: it scales with X and deals damage to each creature with flying and each player, just like Squall Line, while using green mana.WindstormremovalBudget$0.08A scalable green instant that damages each creature with flying, serving as a similar anti-flyer sweeper. It does not hit players, so it is narrower but fills the same board-control role.WhirlwindremovalBudget$0.52A cheap anti-flying sweeper in green that clears all creatures with flying. It is fixed-cost rather than scalable, but it serves the same defensive role against aerial decks.SquallmongerfinisherBudget$0.18Like Squall Line, it can deal damage to each creature with flying and each player, though it is a repeatable creature-based source rather than a spell. It occupies the same anti-flying finisher role.Storm SeekerremovalBudget$0.30A green instant that punishes flying creatures and can also hit a player, overlapping with Squall Line's anti-air and burn plan. It is narrower and not scalable, but functionally adjacent.Heat WaveremovalBudget$0.28This is another anti-flying sweeper that helps stabilize against aerial boards, though it doesn't hit players. It is a strong budget-style substitute for the creature-clearing part of Squall Line.Sandwurm ConvergenceprotectionBudget$0.35While not a direct spell replacement, it locks down flying creatures and prevents them from attacking, covering the same anti-air defensive role. It is a higher-cost, board-warping alternative for green decks.
