Tireless Tribe's deck leans on Survival of the Fittest to tutor creatures and Wild Mongrel/Basking Rootwalla for resilient threats, so Diabolic Edict is a strong unconditional answer that bypasses combat tricks and pump effects entirely. Tormod's Crypt can proactively exile their graveyard to shut off Call of the Herd's flashback, denying a card advantage source. Annul counters Survival of the Fittest, so it stays in. Prioritize efficient removal like Smother alongside Diabolic Edict, and keep countermagic focused on stopping Survival of the Fittest itself rather than its activation payoffs, since Stifle-type answers aren't available in this list.
