Defensive attrition rarely gets a face, but that is exactly the job here: keeping tapped attackers home as blockers undoes the basic math that aggressive decks rely on. An untapped creature has to choose between offense and defense each turn, and the attacker's whole plan is to win that race by forcing the choice. Letting your tapped creatures block means you can swing every turn and still wall up on the back swing, collapsing the tempo advantage attacking earlier was supposed to buy. The flash is what makes the static ability bite: dropping the body at the end of an opponent's declare-attackers step, or in response to a combat math that assumed your blockers were tapped out, turns a clean alpha strike into a stack of bad trades. The 2/1 frame is fragile and intentionally so, since the effect is the engine and the creature is just the housing. As a Human Advisor with this particular wrinkle, it reads more as a defensive enabler dressed in legendary clothing than as a threat, an early-era experiment in handing white a tool that quietly punishes overcommitment rather than answering it directly.
