Pithing Needle is excellent here naming Goblin Charbelcher to completely shut off their primary win condition's activated ability. Stubborn Denial can counter key noncreature spells like Whir of Invention or Goblin Charbelcher itself for just {U} early, since we rarely have a power-4 creature turn one but even the {1} tax mode is relevant against a deck this fast. We trim slow value pieces (Paradise Mantle, Forge Anew) since this matchup is decided almost entirely by whether we can disrupt their combo before they assemble Goblin Charbelcher with an empty or thin library.
