Abzan Greasefang wants to assemble Greasefang, Okiba Boss with a Vehicle like Esika's Chariot or Parhelion II in the graveyard, so Unlicensed Hearse exiles those graveyard targets to shut off their combo while growing into a threat. Duress proactively strips Thoughtseize or Greasefang itself before it can be deployed. Faerie Miscreant and Moon-Circuit Hacker are weak 1-toughness tempo plays that don't interact with their combo plan and die to their removal suite (Bitter Triumph, Collective Brutality). Keep Thoughtseize and your removal suite to interact with Greasefang, Okiba Boss and Esika's Chariot before they combo off.
