Lambholt Harrier

The activated ability is the whole design premise: a plain 2/2 that can spend four mana to peel a blocker away, turning a stalled attack into unblocked damage. The body is deliberately unremarkable because the ability is meant to close games in the late turns of an aggressive curve, not win early exchanges. The math is the restriction that keeps a repeatable evasion-enabler from being oppressive: six mana all told (two to cast, four to activate) means the ability competes with deploying another threat, so you rarely reach for it before the board has committed. The "can't block" clause targets a single creature rather than granting the Harrier its own evasion, which is why the payoff scales with the width of your attack: point it at the one blocker holding back a swarm and the whole team connects. It fills a plain slot as a common-rarity finisher for a red aggro deck that has flooded the board and needs one attacker through, or wants to force a favorable trade. Modest as a card, honest about the job it was printed to do.
