Mono-Red Sligh has zero artifacts or enchantments, making Naturalize dead weight that comes out. Caller of the Claw is a strong flash blocker that can ambush an attacking Ball Lightning or Jackal Pup and turn their removal-heavy, creature-light burn plan into free 2/2 Bears whenever creatures trade in combat. This is a pure race between two aggressive red decks, so prioritize curving out efficiently and using Mogg Fanatic or Siege-Gang Commander tokens to chip through their small creatures. Keep every other card as-is since your goblin synergies out-value their burn-and-creature shell.
