Tangle Spider

The timing line is the entire pitch: Flash plus Reach turns a 3/4 for into an ambush that punishes anyone who commits a flier to the air. The rate is soft by design, because you are paying for the deception rather than the body. Hold up mana, let the attacker decide the sky is clear, then drop a Reach blocker at instant speed and trade up on something that never accounted for it. Spiders had been green's standing wall against flying since the game's earliest sets, with Giant Spider as the plain-vanilla baseline, but those are creatures the attacker sees on the battlefield and plays around. This one rewrites the combat math the moment it resolves, converting a defensive role into a tempo swing. Green does have ways to kill fliers (the color owns the bulk of anti-air removal, from Plummet to mass effects like Hurricane), so what this design adds is not a new answer but a different shape of answer: a blocker that arrives after the commitment is made, when the choice to attack can no longer be unmade. It is less a wall than a trap, and the lesson it teaches about green's relationship to evasion is durable: when green wants to break a stalled air war on its own terms, surprise is one of its sharpest tools.
