Blisterstick Shaman

The pinger packaged as a body. The enters-the-battlefield ping is one of red's oldest support effects, the cheap shot that clears a one-toughness blocker, finishes off a chump, or sends a final point at a face already in burn range. What this Goblin does is staple that effect to a 2/1 that pushes its own damage, so the trigger is a free toll collected on the way to deploying a beater rather than a card spent on its own. The math is the design's whole engine: a 2/1 for three mana is below rate as a vanilla creature, but the point of damage and the willing-attacker body together close the gap. The value lives entirely in arrival, not departure, and that orientation is what makes the card more than a one-shot shock. Because the trigger fires when it enters rather than when it dies, the reward is in re-deployment: a blink or bounce effect that returns it to the battlefield re-fires that single point every time, and recursion turns one creature into a slow stream of pings. That places it squarely in red's tradition of small Goblin Shamans built to be deployed cheaply and often, where the payoff was always in repetition and the sheer number of times you could land the body again.
