Belcher aims to resolve a fast Goblin Charbelcher off Lotus Bloom or ramp, or grind with Sea Gate Restoration and Tameshi, so Damping Sphere slows down explosive multi-spell turns by taxing each additional spell cast in a turn. Vexing Bauble punishes their free-cast Disrupting Shoal and Force of Negation. Wear // Tear on the artifact side can destroy Goblin Charbelcher itself before it goes off, a huge tempo and value swing. While Boromir counters their free-cast Disrupting Shoal and Force of Negation, it is slow at three mana, Blood Moon doesn't stop Goblin Charbelcher from being cast or activated, and extra Legend of Roku copies are too slow against a deck that can kill out of nowhere, so those are cut for proactive artifact hate and taxing effects.
