This is the mirror, so Unholy Heat is excellent removal for their Moonshadow (once it has shed counters), Nethergoyf, and Orcish Bowmasters, scaling to 6 damage with delirium which both decks reach quickly. Surgical Extraction can proactively exile a key Stitcher's Supplier or graveyard piece feeding their Nethergoyf/Street Wraith plan, disrupting their delirium and escape lines. We trim some card selection for more interaction since both decks are racing to assemble delirium and removal matters more than extra Bauble triggers in a mirror. Keep Thoughtseize and Flare of Malice as premium disruption and removal that both decks rely on to win these races.
