Tireless Tribe is a fast combo deck that wins by discarding to Tribe, casting Inside Out to flip power and toughness, and attacking for lethal or Flinging for damage — your primary goal is to kill Tireless Tribe before they can execute the combo, and the additional copies of Go for the Throat alongside Cast Down give you eight interaction pieces for their key creature. Duress comes in to strip Inside Out, Prismatic Strands, or Loran's Escape from their hand, attacking the combo's protection suite before they can deploy it. Faerie Macabre provides both a flash blocker and critical graveyard disruption against Pursue the Past, which can rebuy Inside Out and Faithless Looting to reassemble the combo after disruption. Breath Weapon answers their wide board of Sneaky Snacker, Aurora Eidolon, and Sandstorm Eidolon cleanly. Lembas and Krark-Clan Shaman come out because life gain is largely irrelevant against a one-turn-kill combo, and the Shaman's -1/-1 sweeper is too slow and easily blanked by their protection instants.
