Goblins is an aggressive red deck that wins by curving Goblin Lackey into Goblin Warchief and Goblin Piledriver, threatening lethal damage before your Dreadnought can stabilize the board. Blue Elemental Blast and Hydroblast are your primary tools, answering Goblin Warchief, Siege-Gang Commander, Goblin Piledriver, or any direct threat at instant speed. Essence Flare is a key weapon here — slapping it on Goblin Lackey or Goblin Piledriver neuters their offense permanently, as the cumulative upkeep will drain them of their attacker without you spending a counterspell. Keep Stifle up for Goblin Matron and Goblin Ringleader triggers as well as Wasteland and Rishadan Port activations, since denying their mana and card advantage engine is critical. Peek and the pitch-cost cards (Misdirection, Thwart) come out since you need to maximize mana efficiency and Blue Elemental Blast effects are strictly better answers in this matchup.
