Fire Whip

Strap a poker onto your creature and you have turned a body into a repeatable pinger, the same structural trick designers were exploring elsewhere through enchantments rather than through creatures with the ability baked in. The clever part is the back end: a sacrifice clause that lets the Aura cash itself out for one last point of damage. Timing matters more than it looks. Because an Aura goes to the graveyard as a state-based action the instant its host dies, you cannot wait for the creature to die and then sacrifice it; you have to respond to the removal spell or ability while the creature is still on the battlefield, sacrificing the Aura with the kill spell on the stack to squeeze out that final point. Pull it off and you trade your two-mana investment for a guaranteed Shock-minus-one before the host falls; miss the window and the enchanted creature dies clean, taking your card with it. The tap ability also costs the creature its attack, so every turn poses a real choice: swing for combat damage, or sit back and chip in one point at a time. It is a small machine for grinding out attrition, the kind of incremental engine that suits patient, defensive boards rather than aggressive ones. The rate looks thin by modern standards, but the architecture (turn a creature into a damage source, then collect on the enchantment for a parting shot) is a clean early expression of the pinger-on-an-Aura idea.
