Jurin, Leading the Charge
The math on the attack trigger runs backward from where anthem effects usually point. Most swarm payoffs reward you for going wide: the more attackers you commit, the harder they land. This one scales off the defender's board instead, handing each of your attacking creatures a pump for every creature the player it's attacking controls. Swing into a clogged battlefield and your team balloons; swing into an empty one and the trigger does nothing. That inversion pairs with the compulsory-block line: a hasty 4/6 that must be blocked if able forces a body to peel off the defensive wall and eat it. And because the trigger resolves in the Declare Attackers step, the buff is locked in before blockers ever come down, sized entirely by how many creatures the defender has committed to that turtled board. Blocking Jurin does not shrink the anthem; it just trades a blocker into a 4/6 while the rest of your team keeps the swelled numbers. The design asks you to swing into resistance rather than around it: the more a player hides behind bodies, the larger the alpha strike Jurin turns those same bodies into. It is a payoff built for the exact moment a ground stall is supposed to protect the player being attacked, and instead makes that stall the fuel that breaks it.
