Swirling Sandstorm

Threshold board sweepers were Judgment's answer to a recurring red problem: how do you give the color a board wipe without giving it a board wipe? The conditional is the answer. Filling seven cards into the graveyard before turning this on is real work for a deck that wants to be casting cheap creatures and burn, so the payoff scales with how committed you are to the graveyard plan rather than handing red an unconditional five-to-the-team for four mana. Once threshold is online, five damage to each non-flier clears most of what a red deck cannot already burn out, while the flying exemption preserves your own evasive threats and quietly tells you what to build alongside it. The card belongs to a school of design that asked red to earn its sweepers through deck construction rather than mana cost, a tradition that runs back through Earthquake and forward to the various "deal X to everything without flying" effects that pepper red's history. What separates this one is that the condition is binary and free: hit seven, and the rate snaps from dead card to one of the harder hits red ever gets on a single sorcery. The flying clause is doing double duty, both as a thematic carve-out and as a deckbuilding signpost, pointing whoever sleeves it toward a graveyard-fueled aggro shell that closes through the air while the ground burns.
