Dimir Tempo combines discard, free counterspells, and efficient threats like Tamiyo and Murktide Regent, so we want to race while disrupting their disruption — Surgical Extraction lets us permanently answer a Snuff Out or protect a reanimated bomb from being exiled by Barrowgoyf triggers or graveyard hate they bring in. Chain of Smog is excellent at stripping their hand of Force of Will and Daze in one shot before we commit Reanimate or Shallow Grave. Trim Raph & Mikey and Borborygmos since they're too slow against a deck applying steady pressure with Orcish Bowmasters and Kaito. Use Thoughtseize and Unmask early to clear the way, since their own Thoughtseize and Bowmasters punish us for over-extending — try to win with a single resolved Griselbrand or Atraxa rather than multiple threats.
