Goblin Marshal

Echo turns this from a six-mana goblin into a question about how badly you want the second wave. Pay it and the creature stays, banking on the body and the eventual death trigger; let it lapse and you've spent six mana for four 1/1 Goblins across two turns, two on the way in and two on the way out, with the sacrifice itself feeding the dies trigger. That refusal-as-feature is what makes the design clever: the echo cost isn't a tax you grudgingly pay so much as an option you can decline for value, since the card was built to give you tokens at both ends of its life. Most echo creatures of its era punished you for skipping the payment; this one rewards it, because the enters-and-dies clause means the cheapest way to extract full value is often to never pay echo at all. That double-trigger shape made it a natural fit for sacrifice and token strategies long before "aristocrats" was a word anyone used, and it reads as an early sketch of the goblin-token engines that later sets would build out more directly. The 3/3 body is almost incidental; what you're buying is a guaranteed swarm of expendable Goblins on a flexible schedule, payable now or deferred, with the sacrifice clock doing the deferring for you.
