Goblin Turncoat

Most regenerators charge mana per shield; this one charges bodies, converting a recurring tax into a one-time board tax that scales backward as your Goblin count thins. That inversion is the genuinely clever thing here: each block or burn spell becomes a question of whether one Goblin is worth more than another, and the engine consumes the very thing it exists to protect. It demonstrates the cost-shifting logic Wizards leans on to keep regeneration in check, trading a repeatable mana drip for a finite sacrifice well. In practice, though, the math works against the tribe it belongs to. Goblins want to attack, not trade, and a back-of-the-curve regenerator that eats its own swarm reads as a stress test of how far tribal density can be pushed before it cannibalizes itself. The type already had louder sacrifice payoffs (Siege-Gang Commander turning bodies into reach, Goblin Sharpshooter recurring its ping) that did more with the same fodder. What was left for a 2/1 that survives by spending its kin was a footnote slot in a creature-saturated era, interesting for the design wrinkle on its activation line and largely ignored everywhere else.
