Wall of One Thousand Cuts

Defender is a promise the creature will never swing back; this one keeps a mana in reserve to break that promise the moment the board turns. On defense it flies and blocks like a proper 3/5 wall, absorbing the evasive attackers most ground-bound blockers cannot touch. When the pressure reverses and the opponent is the one on the back foot, the same body reaches over to close the game, converting a stat line built to endure into one that ends turns. The flying does double duty: it is the reason the wall blocks well and the reason the attack actually connects, so a single white mana turns a purely reactive asset into a threat without asking you to commit anything until the window opens. That deferral is the discipline in the design; you never pay for reach you do not need, and the card sits harmlessly on the table until the exact moment aggression is safe. Walls that secretly want to attack are an old idea, from the enchantments that granted every defender permission to swing down to individual creatures carrying that permission themselves. This is the self-contained version: one card, one mana, wall to finisher on demand.
