Mono-Green Eldrazi wants to curve into cheap mana dorks and artifact-lands before dropping huge Eldrazi threats, so our best plan is to disrupt their mana development and race before Emrakul or Devourer of Destiny come down. Brotherhood's End destroying artifacts with mana value 3 or less hits Springleaf Drum, Vexing Bauble, Soul-Guide Lantern, and Talisman-type mana rocks (though note it does not hit their lands). Untimely Malfunction destroys an artifact outright (e.g., Vexing Bauble) or can redirect their removal. Artist's Talent and Hex Magic are too slow and card-disadvantageous against a deck that just wants to assemble a big threat; we need every card advancing our storm plan.
