Scuzzback Scrounger

The trick here is that the cost of the ability is paid in your own creatures' toughness, and the payoff refills your manabase. Blight 1 wants a target that either shrugs off the counter or actively wants it: a token you were going to trade away, something with a death trigger you are trying to fire, a creature already destined for the graveyard. Turned on itself, this Goblin is a short fuse: 3/2, then 2/1, then dead to the second activation once the counter drops it to 1/0. The counter is not incidental friction; it is the resource being converted into acceleration, which puts a hard ceiling on how long any single body can sustain the engine. Timing sharpens it further: the trigger resolves before combat, so the Treasure is live the turn it is minted rather than sitting idle until your next turn. Read alongside a wider -1/-1 counter theme, the card reframes what looks like a drawback as a fuel line: every point of toughness you spend comes back as a mana of any color, and the deck decides each turn whether to feed the counter to this Goblin or to something that would rather be smaller. It is a converter, taking a stat usually treated as a liability and turning it into fixing and ramp.
