Boros Moxite builds an artifact-heavy board with Melded Moxite, Rustvale Bridge, and various equipment like Ragged Short Spear to power Dispatch and Galvanic Blast, so artifact removal and hand disruption both have good targets. Undergrowth Leopard can sacrifice itself to destroy a Melded Moxite or Lembas before it generates value, though it won't touch the indestructible Rustvale Bridge. Mesmeric Fiend strips a key removal spell like Lightning Bolt or Galvanic Blast, or an equipment like Ragged Short Spear, protecting our bigger creatures from their aggressive plan. Gatecreeper Vine and Quirion Ranger are too passive against a deck built to apply steady pressure with efficient creatures and equipment.
