Thalia, Guardian of Thraben taxes their Brainstorm, Ponder, Force of Will, and removal suite, slowing down their cantrip-into-threat gameplan considerably. Surgical Extraction can strip a copy of Murktide Regent's delve fuel indirectly by exiling key graveyard cards, or answer a resolved Bilbo, Thief in the Night's recursion plan by removing targets from their graveyard. Witch Enchanter is weak here since they run few artifacts/enchantments worth destroying, and Boggart Trawler's graveyard exile is redundant with better tools. Keep Thoughtseize and Wasteland at full count since proactive disruption and land destruction are premium against their tempo plan.

Disruptor Flute naming Thought-Knot Seer, Kozilek's Command, or Eldrazi Linebreaker taxes their most impactful repeatable threats and interaction out of a game where they're often mana-flooded with colorless sources anyway. Our Swords to Plowshares and Solitude answer their big colorless bodies (Reality Smasher, Sire of Seven Deaths) cleanly since those spells exile rather than fight through combat stats. Witch Enchanter and Pre-War Formalwear are cut as they're too slow against a deck that curves out with 4/4s and 5/5s starting turn one via Ancient Tomb and Eldrazi Temple.

Disruptor Flute is excellent naming Ocelot Pride, Ajani, Nacatl Pariah, or Guide of Souls to shut off their key engine pieces while taxing rebuys. Thalia, Guardian of Thraben punishes their noncreature-heavy removal and enchantment suite (Static Prison, Goblin Bombardment) by taxing them a mana. Our own Swords to Plowshares and Solitude are premium answers to their small creatures, so we keep those at full count. Witch Enchanter and Pre-War Formalwear are cut since they're slow value pieces that don't affect the token-swarm race, and Boggart Trawler's graveyard exile is low-impact here.
