Greasefang decks win by reanimating Thundering Broodwagon or crewing Esika's Chariot quickly, so Unlicensed Hearse shuts off the Greasefang, Okiba Boss engine by exiling the graveyard target before it can be returned. Duress strips their vehicles or removal (Bitter Triumph, Fatal Push) before they matter, though it can't take Greasefang itself since it only hits noncreature, nonland cards. Withering Curse gives us a sweeper that kills their 2/2 Cat tokens and small creatures like Professor of Symbology, but without lifegain it is only -2/-2, so Formidable Speaker (a 2/4) survives it. We trim the slower Badgermole Cub and Sentinel of the Nameless City copies, which don't pressure the opponent's plan fast enough, and cut one Culling Ritual since Esika's Chariot and Thundering Broodwagon cost too much to be hit by it. Keep Go for the Throat in to answer Greasefang itself before the vehicle recursion starts; Fatal Push only kills Greasefang (mana value 3) if revolt is on, so treat it as a cheap answer to their smaller creatures otherwise.
