Arms of Hadar gives -2/-2 to all of an opponent's creatures, which kills Slippery Bogle, Gladecover Scout, and Silhana Ledgewalker before they're enchanted, though it won't matter once Ancestral Mask or Armadillo Cloak resolves. Extract a Confession is a poor fit since their hexproof creatures can't be forced to be sacrificed as the biggest threat reliably and Bogles usually only has one creature on board anyway making it symmetric with their choice. Keep Dispatch and Counterspell as your primary interaction — Dispatch can still tap down an enchanted threat and Counterspell stops their key auras like Rancor or Armadillo Cloak before they resolve.
