Deafening Silence slows down their one-mana Thoughtseize into a blink/value turn by capping them to one noncreature spell per turn, disrupting their Ephemerate and removal sequencing. Enter the Avatar State can push a key threat like Vengevine or Hollow One through their Solitude and Orcish Bowmasters-heavy removal suite by granting hexproof for a lethal attack. Burning Inquiry is poor against a deck full of cheap, replaceable cards like Mishra's Bauble-style value pieces that they won't mind discarding, and it can even feed their graveyard-adjacent Overlord of the Balemurk mill triggers indirectly, so cut it along with a Street Wraith. Keep your proactive discard-and-threat plan since you want to beat down before they stabilize with Flickerwisp and Phelia value.
