Goblin Rabblemaster

Left unanswered for even a single turn, this is a clock that compounds. The token comes for free at the start of every one of your combats, so the board grows whether or not you commit any more resources, and the attack trigger turns that widening board into reach: each Goblin swinging beside it pumps its power, so a board that looks like a pile of 1/1s closes a game faster than any of them suggests individually. The forced-attack clause is the part players underrate. It is usually written off as downside, but in an aggressive shell it is the engine doing exactly what you want anyway, and against a stalled board it pressures the opponent into combat math they would rather avoid. The whole package sits on a 2/2 body for three mana, which is the design tension the card resolves: a permanent that demands an immediate answer but costs little enough that trading a removal spell for it already feels like you fell behind. That untouched-for-a-turn-and-you-lose quality is why it became a yardstick for how much pressure a single three-drop is allowed to generate, and why later go-wide red threats tend to come with a tax, a smaller body, or a slower start that this card never had to carry.
