Scuzzback Scrapper

The hybrid pip means either color of a red-green attrition shell can run this Goblin, and the whole pitch is what its single point of power leaves behind. Wither converts every point of damage it deals to a creature into permanent -1/-1 counters, so when it trades with a blocker, that blocker does not just absorb a hit and reset at end of turn: it shrinks for good. Send it into a 3/3 and the 3/3 ends the exchange a 2/2, even though the Scrapper itself dies on the way in. That is the actual bargain here, and it is the part the body keeps honest. A 1/1 with no first strike does not survive combat to do this repeatedly; it does its damage once, then dies. So this is a one-shot tax disguised as an attacker: you spend the creature to permanently dent something larger, and the exchange favors you as long as what you erase is worth more than a one-drop. Note the asymmetry built into Wither itself: the counters only apply to creatures. An unblocked swing connects with the player as ordinary one damage, nothing special, which means the defender's incentive runs backwards from the usual. Letting a 1/1 through is the safe play; blocking it is what costs them. The design uses a permanent shrinking effect to make a throwaway body genuinely unprofitable to fight, while keeping the rate fair: it only ever bites once.
