Tireless Tribe is a fast combo deck that wins by discarding cards to inflate Tireless Tribe's toughness, then flipping it with Inside Out for a lethal one-shot attacker. Your primary disruption is Journey to Nowhere and Thraben Charm to answer Tireless Tribe proactively, with Prismatic Strands as a safety valve if they successfully assemble mid-combat. Faerie Macabre comes in to disrupt their graveyard engine — particularly Pursue the Past (which needs escape fodder) and Faithless Looting — and can be cast for free at instant speed to blank a Thrilling Discovery setup. Pulse of Murasa provides a life buffer against Lightning Bolt and Sneaky Snacker chip damage while also recurring a key creature or enchantment if needed. Ancient Grudge has no targets in this matchup and is a clean cut.
