Tireless Tribe is a fast combo deck that wins by discarding cards to grow Tireless Tribe's toughness and then casting Inside Out to flip its power/toughness for a lethal swing. Gut Shot answers Tireless Tribe at zero mana cost before they can begin stacking discards, and is your most efficient disruption against the combo. Blue Elemental Blast counters their red setup spells — Faithless Looting, Thrilling Discovery, Pursue the Past, and Lightning Bolt — denying them the card selection and velocity they need to find the combo. Keep your remaining Counterspells and Dispels in reserve specifically for Inside Out; letting their enablers resolve is acceptable as long as you can answer the combo piece itself. Sleep of the Dead and Deem Inferior are too slow or mana-intensive against their goldfish speed, so trimming them frees slots for more proactive disruption.
