Squall

Green has always paid a tax to interact with the sky, and this is among the bluntest forms that tax takes: an anti-flying sweeper that does nothing to anything on the ground. Two damage to each flyer is a narrow, asymmetric clear that wipes the squadrons of small evasive creatures green can't otherwise touch while leaving the caster's own grounded board untouched, an answer built around the color's central weakness rather than a general-purpose removal spell. The design discipline is the global condition doing the limiting work: because it hits each creature with flying rather than choosing a target, it ignores hexproof and shroud entirely and clears the whole air at once, but it also reads as dead in any matchup without a flying presence. That conditional ceiling is what the rate is bought with. It belongs to a long green tradition of board-state hosers that ask you to be right about what you're facing rather than to be flexible, sitting alongside the Hurricane and Whirlwind variants green has reprinted in different sizes whenever the format's evasion threat got out of hand. As a sorcery it cedes the instant-speed window those storm-themed sweepers sometimes offered, so it can't ambush attackers mid-combat; it functions as a proactive board-clear on your own turn, a way to answer a developed flying board before it swings rather than a trick to blunt the swing itself.
