Goblin Lookout

Sacrifice one Goblin and every Goblin creature swings for two more: that scaling ratio is the whole reason this reads differently from a flat pump. Most Goblin payoffs of its era spent a body to deal a fixed chunk of damage (Goblin Sledder shoves a single creature, Mogg Fanatic throws itself for one). Here the bonus grows with the width of the board, so the more Goblins survive to attack, the more each sacrificed one is worth. The body is fragile and the tap requirement keeps it from both pumping and attacking in the same turn unless something untaps it or grants vigilance, but that is the price of an effect that can convert a stalled board into lethal in a single attack step. It rewards the redundant, recursive Goblin shells that flood the battlefield faster than they can profitably trade: every creature past the first is both a potential attacker and potential ammunition. The tension is real, because converting an attacker into a pump means weakening your board to make the survivors hit far harder, a trade that only pays when the team is already crashing in. In a tribe built on throwaway bodies and chained sacrifice triggers, it is the closing piece that turns a pile of expendable one-drops into a finisher.
