Goblin Firestarter

Compare it to Mogg Fanatic and the difference is a single clause about when you can pull the trigger. Both are one-mana 1/1 Goblins that sacrifice to deal a point of damage to any target; the Fanatic does it at instant speed, which is what made it a defining red one-drop for years. It could ambush a blocker, snipe a creature across the table, or shove the final point through after combat math had resolved. This Goblin can only fire on its controller's turn, and only before attackers are declared. That single sentence amputates almost everything that made the effect valuable. You cannot hold it as reactive removal, cannot wait to see how blocks develop, cannot even sacrifice it after committing to an attack to finish a damaged blocker. The damage has to be spent proactively: clear a blocker before you swing, or burn a creature on your own clock and nothing else. This kind of awkwardly fenced timing window is a fingerprint of the Portal design philosophy, where the rules engine was deliberately stripped down to keep instant-speed decisions away from new players. What you end up with reads like a premium aggressive Goblin and plays like one with its reactive layer surgically removed: the body and the burn are intact, but the interaction that gave the original its reputation has been sawn off at the timing clause.
