Gruul Goblins is a tribal aggro deck that wins through Goblin Lackey cheating threats into play and Goblin Ringleader refueling the hand — your discard suite of Duress, Cabal Therapy, and Funeral Charm is critical for disrupting these key pieces early. Engineered Plague naming Goblin neuters almost the entire board simultaneously and is your most powerful card in this matchup. Perish as a sorcery sweeper hits everything in their deck except Goblin King, providing additional reset potential. Smother and Snuff Out come out because Engineered Plague is a more efficient answer to their swarm, and one Ravenous Rats is trimmed since their deck refills via Ringleader making the discard less impactful in topdeck wars. Phyrexian Negator and Hypnotic Specter remain in as your primary clock — getting a Specter through early can be backbreaking, and the combination of hand disruption plus a fast clock is your primary game plan.
