Scorch Spitter

The reward is folded into the attack step, and that placement is the entire design. A one-power beater wants to be blocked as little as anything can, and the built-in ping exists precisely for the turns when the body gets stopped: attack into a blocker, the 1/1 dies in combat, but the point of damage lands on the player or planeswalker anyway. Decoupling the damage from the combat result is what lifts it above a vanilla one-drop; a chump block spares the opponent their board, not their life total. The catch is the ceiling. The ability keys off attacking rather than entering or a static tick, so it does nothing sitting back, and the damage is a flat 1 that never scales with power pumps, only with additional attack triggers. That makes it a piece for a deck treating life total as a resource to be shaved rather than a body meant to win a race on its own: a persistent leak that ignores the ground stall other small creatures get caught behind.
