Mogg War Marshal

Echo is usually a tax that makes you pay for a creature twice or watch it walk off the table, and most echo creatures became trivia the moment the mechanic stopped seeing print. This goblin inverted the drawback into a choice that pays out either way. Decline the echo and the creature is sacrificed at your next upkeep, but the enters-and-dies clause means you bank an ETB token going in and a death token going out: two 1/1 Goblins from one card, with the cheap line costing you nothing extra. Pay the echo and you keep the original body plus its first token, trading the death trigger for a stickier board. Both outcomes convert the whole card into expendable permanents, which is exactly the currency a sacrifice deck spends. The real engine is that each body is a discrete trigger for anything that watches creatures arrive, leave, or get sacrificed; a recurring sacrifice outlet can feed the war marshal in piecemeal, milking separate enter-and-die events out of the same card. That reframes it as less a creature than a small, self-metering supply of ammunition: a design built for goblin aggro shells that treat individual bodies as fuel rather than threats, where the echo cost is not a penalty but a dial for how much board you want to leave standing.
