Bloodstone Goblin

Kicker has always been an additional cost searching for a payoff beyond the spell it rides on, and this Goblin is built to be that second payoff. The trigger doesn't care what you kicked or how much you paid; it fires whenever any spell you cast was kicked, converting every overpaid spell in the deck into an incidental combat pump. That reframes kicker from a one-spell value question into a board-wide tempo plan: the menace matters more than the +1/+1, because a kicked spell cast in your first main phase forces two blockers on this Goblin in the combat step that follows, pushing damage through where a single blocker would have absorbed it. Timing is the whole trick, though. The buff lasts only until end of turn, so a kicker spell held for a post-combat main phase does nothing for the attack that already happened. It rewards committing your extra mana on offense before combat, not banking it for a defensive turn. The 2/2 body is deliberately undersized so the trigger has to carry the card, and it only carries in a deck dense enough with kicker spells to fire it more than once a game. That dependency is the pitch: it wants kicker built as a theme rather than a splash of a few flexible spells. Strip out the kicker density and the line of text goes inert, which is the design intent: a payoff that pays nothing unless you build toward it.
