Bogles relies on hexproof creatures like Slippery Bogle and Gladecover Scout loaded up with Auras, so targeted removal like Snuff Out, Cast Down, and Agony Warp is completely dead against their key threats and countermagic is your main real answer before Auras resolve. Arms of Hadar targets the player rather than their creatures, so hexproof doesn't stop it, and it can kill a bare Slippery Bogle or Gladecover Scout (both 1/1) before they get enchanted, so it's worth the swap in. Extract a Confession is a poor fit since it only forces a sacrifice, and the opponent chooses which creature to give up, so they can sacrifice a bare creature and keep the one carrying their Auras. Prioritize countering their key Auras (Rancor, Armadillo Cloak, Ethereal Armor) with Counterspell, since once an Aura resolves on a hexproof creature it is very hard to answer. Dispel only counters instant spells, so it can't stop their Auras.
