Lightning Bolt is poor against 13/13s and 6/6s, so both copies come out, and we trim one Stubborn Denial since it only hits their noncreature spells. Consign to Memory stays in: Emrakul, Devourer of Destiny, and the devoid Basking Broodscale and Sowing Mycospawn are all colorless spells it can counter, as is Kozilek's Command, and it can also answer triggered abilities. Obsidian Charmaw is an efficient flying body that also destroys a nonbasic land such as Eldrazi Temple, Ugin's Labyrinth, or Urza's Saga, cutting off their ramp. Wear // Tear is flexible: Wear destroys artifacts like Soul-Guide Lantern, Blade of the Bloodchief, Springleaf Drum, or Haywire Mite, while Tear destroys enchantments, which includes Urza's Saga since it is an Enchantment Land. Keep Fatal Push and Leyline Binding in since they efficiently answer Basking Broodscale and the big Eldrazi respectively.

The combo wins through Blade of the Bloodchief plus Basking Broodscale, so Wear // Tear's artifact-destruction mode is premium removal for Blade, and it can also hit a Soul-Guide Lantern or Vexing Bauble if needed. Obsidian Charmaw is a strong flying clock that doubles as land destruction against Eldrazi Temple, Ugin's Labyrinth, or Urza's Saga, slowing the ramp that assembles their pieces. Lightning Bolt stays in because it kills Basking Broodscale even after it adapts to a 3/3, and Fatal Push can also kill Broodscale (mana value 2) before the loop goes off. Push cannot target Blade of the Bloodchief since it is an artifact, so Leyline Binding and Wear // Tear are the answers there. Consign to Memory stays in as well: Basking Broodscale (devoid) and Blade of the Bloodchief are colorless spells it can counter, and it can also counter Broodscale's Spawn-creating trigger and Blade's counter-adding trigger, which makes it a strong way to break the loop. Hold Stubborn Denial for Blade and other noncreature spells, and keep removal for the pre-combo turns. To make room, we trim Phelia and Quantum Riddler, which do the least to interrupt their combo.

This is a fast noncreature-spell-driven aggro deck, so High Noon is excellent, slowing their Cori-Steel Cutter flurry and burn chains to one spell per turn while we race with better bodies. Lightning Bolt trades down into their efficient low-toughness threats like Monastery Swiftspear (a 1/2) and Dragon's Rage Channeler (a 1/1) less favorably than our removal already in the deck (Fatal Push, Leyline Binding), so trim it for more impactful interaction. Consign to Memory is weak here since most of their key threats are creature spells, but the extra copies still snipe Mishra's Bauble triggers and colorless noncreature spells; keep Stubborn Denial mainboard count low since they hold up little mana to tax. Prioritize racing with Ragavan, Territorial Kavu, and Scion of Draco while using Fatal Push and Leyline Binding on Dragon's Rage Channeler and Slickshot Show-Off.
