Fodder Launch

Goblin removal that bills the creature's controller as much as the creature. The -5/-5 kills almost anything, but the five damage to that creature's controller is where the design tips its hand: this is not a clean answer, it is a punish, aimed at a board that already treats its own bodies as ammunition and is glad to convert one of them into a corpse plus a quarter of an opponent's life total. The sacrifice clause is the price and the point at once, asking you to spend a Goblin to fling a Goblin's worth of carnage downrange. In an aristocrats shell that cost is nearly free, since the creature you toss was already headed for a sacrifice outlet; outside one, the additional cost makes the spell impossible to cast on an empty board, and as a sorcery it cannot ambush a creature mid-combat or answer a threat at the end of a turn. That dependence is the leash on it: a four-mana double-bladed removal-and-burn spell would be unreasonable if it asked nothing in return, so the design gates the upside behind a tribe you have to commit to and a body you have to give up. It plays like a finisher wearing removal's clothes, ending a stalled board not by clearing a blocker but by aiming the whole transaction at the player behind it.
