Sting-Slinger
Blight reframes an old red idea: the pinger that hits players instead of creatures, paid for not with mana alone but with your own board's flesh. Each activation demands , taps the Goblin, and shrinks one of your creatures with a -1/-1 counter, which turns a repeatable two-damage reach engine into a resource-management puzzle. The friction runs in two directions at once. Feed the shrink onto your own attackers and you erode the clock you built to close the game; feed it onto expendable bodies (tokens, a one-drop that already did its job) and you spend real cards to keep the burn flowing. That tension is the whole design: the ability is genuinely repeatable, but the ammunition is your own team rather than a life total or a card in hand, so the deck around it has to manufacture creatures worth destroying. The natural home is a sacrifice-and-tokens shell where blighting doubles as a trigger, shrinking fodder toward a death you wanted anyway while chipping the opponent for two. It sits in a lineage of goblins that treat their own kind as ammunition, but where those older designs launched a single creature at a single target, this one bleeds its own board to bleed the whole table, on any turn you can spare two mana and a body you can afford to wound.
