Eldrazi's whole plan runs through Ancient Stirrings, Malevolent Rumble, and reanimating big threats via Emrakul casting cost reduction, so Grafdigger's Cage shuts off their ramp payoffs and graveyard recursion; note Nihil Spellbomb is only 1 copy so adjust accordingly. Thoughtseize is weak since this is a nonland-permanent ramp deck that doesn't care about losing a card from hand once lands and threats are already down. Obsidian Charmaw comes in as a cheap flying beater that also blows up their Eldrazi Temple or Urza's Saga, and it gets cheaper the more colorless lands they run. Surgical Extraction can snag an Ancient Stirrings or Malevolent Rumble to disrupt their card selection engine. Keep the full removal suite since Devourer of Destiny, Emrakul, and Sire of Seven Deaths are all big bodies that need answers.

This is the full mirror match, so Unholy Heat is strictly better removal than Lightning Bolt once delirium is online (which happens fast in this deck), dealing 6 to kill Moonshadow or any Nethergoyf outright instead of Bolt's 3. Surgical Extraction can proactively exile their Stitcher's Supplier, Street Wraith, or key graveyard piece to blunt their Nethergoyf and Detective's Phoenix plans, and the mirror is often decided by graveyard resource races. Keep removal count high since both decks are full of efficient threats that need to be answered immediately. Cutting one Mishra's Bauble slightly reduces card velocity but the upgrade in removal quality is worth it in a mirror where mutual delirium is nearly guaranteed by turn 2-3.

Esper Control leans on Flooded Strand, Arid Mesa, and Polluted Delta fetches plus Day's Undoing, so Ashiok, Dream Render shuts off their fetch lands, and its -1 can exile their graveyard (or mill us to help fuel delirium for Nethergoyf). Mishra's Bauble is low-impact against a deck like this, especially with Narset limiting us to one draw each turn. Obsidian Charmaw is a 4/4 flying threat (it has no haste, so it can't attack the turn it enters) that is relevant against their mostly noncreature deck, and its enters trigger can destroy a nonbasic land like Geier Reach Sanitarium, Otawara, or one of their fetches or dual lands. Surgical Extraction can exile the remaining copies of a key card like Solitude or Orim's Chant from their hand and library once one has hit their graveyard.
