Abzan Greasefang wants to assemble Greasefang, Okiba Boss with Esika's Chariot or Thundering Broodwagon quickly, so Scorching Shot and Redcap Melee give you clean answers to Greasefang itself (4/3) or Professor of Symbology before the combo goes off. Monstrous Rage is weak here since they carry plenty of removal (Bitter Triumph, Fatal Push, Thoughtseize) to two-for-one the enchanted creature, and a couple Kumano Faces Kakkazan come out in favor of more proactive interaction since racing alone risks losing to a returned Vehicle attacking for a lot of damage. Try to race quickly and hold up removal for their Greasefang or crewed Vehicles rather than letting the game go long.
