Boros Dwarves is an equipment-and-creatures aggro deck built around Leyline Axe, Basilisk Collar, and Doc Ock's Tentacles; while their Equipment are noncreature spells that Spell Pierce can counter, trimming a copy makes sense as it cannot counter their creatures, while Together as One is too slow against this speed. Urgent Necropsy is versatile removal that can hit a creature and an Equipment simultaneously, directly addressing their gear-up plan. Heritage Reclamation strips a key Equipment like Leyline Axe or Basilisk Collar. Rely heavily on Deadly Cover-Up and Day of Black Sun as your primary answers to their low-curve, wide aggressive board, and keep Requiting Hex and Bitter Triumph for early interaction.
