Gruul Ramp deploys big nonartifact threats like Jewel Thief, Primordial Pachyderm, and Writhing Chrysalis, so Go for the Throat is excellent, efficient removal here. Troublemaker Ouphe can bargain away one of your own artifacts (like a spent Ichor Wellspring or Nihil Spellbomb) to exile an artifact or enchantment of theirs, hitting mana-fixing pieces like Utopia Sprawl or a Treasure token before it's used, though it's most useful if they bring in artifact-based sideboard cards. Trim slower card-advantage pieces like Eviscerator's Insight and Lembas since you want to prioritize efficient interaction against their bigger bodies. Keep your removal suite proactive to answer their ramp-fueled threats before they take over combat.
