Goblins is an aggressive tribal deck that wins through synergy — Goblin Lackey into Siege-Gang Commander or Goblin Ringleader refueling hands make this matchup punishing if you stumble. Engineered Plague naming Goblin is your best card and essentially locks them out of combat damage and Mogg Fanatic pinging, so prioritize finding it early. Infest sweeps a developed board at instant... rather, at sorcery speed and pairs well with Plague to clear out anything that squeaked through. Powder Keg handles Goblin Warchief and other threats that slip past Plague. Ravenous Rats and Nantuko Shade come out because hand disruption is slow against a deck that can rebuild via Ringleader, and Shade is too mana-intensive when you need to hold up removal; Smother, Diabolic Edict, and Cabal Therapy remain to pick off key threats like Lackey on turn one.
