Falter

Aggressive red has always needed a way to break a board stall, and the cleanest version of that effect simply switches off ground blockers for a turn: anything without flying loses the ability to stand in front of an attacker. Everything depends on the timing. Held at instant speed until the opponent has committed creatures to defense, it converts a gridlocked beatdown into a lethal alpha strike, and where a removal spell clears one chump, this scales with the whole attacking team in a single card. The flying clause is the deliberate hole in the design: airborne defenders can still block, which keeps the spell to its lane as a ground-pounder's tool. A blanket "creatures can't block" line would make any wide board lethal with no discrimination at all, so that restriction is the price the card pays for its reach. The lineage runs in two directions: effects that grant unblockable to your attackers, and effects like this one that subtract the opponent's blockers from the math. The trade is constant across both: a temporary, board-wide opening in exchange for spending a card on tempo rather than a permanent edge. It reads as a combat trick and functions as a finisher, the closer for a race that has dragged on past the point where the defender stopped racing back.
