Boneclub Berserker

The 2/4 body is the tell. This is a Goblin lord that has abandoned the anthem entirely: it pumps only itself, and only in raw power, scaling +2 per other Goblin while everyone around it stays whatever size they were printed. A wide board of three or four goblins turns this into a 8/4 or 10/4 that has to attack alone to matter, since none of that bonus spills onto the horde. The four toughness is doing quiet work in the design: it lets the berserker survive the kind of chip damage that a glass-cannon body would fold to, and it keeps the card relevant defensively on turns when the swing is not there. Where a traditional Goblin lord asks you to go wide and profit from the aggregate, this one rewards the same board state but cashes it in through a single threat, which changes the math of every block and every burn spell pointed at it. Kill the berserker and the goblins are just goblins again; leave it and one creature carries lethal. It sits in the older tradition of self-only scaling beaters, the kind of card that gets bigger the more the rest of the board commits, but priced and bodied to survive the turn cycle rather than die to the first piece of interaction.
