This is a graveyard and colorless-permanent combo deck built around Emrakul, the Promised End and Devourer of Destiny; Rest in Peace shuts off Malevolent Rumble/Ancient Stirrings value and stops Blade of the Bloodchief recursion while denying flashback-free but graveyard-fueled plans. High Noon slows their explosive multi-spell turns from Urza's Saga and burst-casting Eldrazi. Counterspell and Spell Snare are weak since much of their threat suite is colorless permanents cast for value rather than countermagic wars, so cut copies for the more proactive hate pieces. Keep Wrath of the Skies, Prismatic Ending, and Solitude in as your main way to answer Basking Broodscale and Devourer of Destiny before they scale up. Kaheera can come in as extra interaction/body if you want a low-cost buffer, but the core plan is choking their card advantage engines with Rest in Peace and High Noon.
