Esper GenericBlink leans on Solitude, Thoughtseize, and Flickerwisp/Phelia/Ephemerate value loops rather than artifacts, so our artifact/enchantment hate is mostly a body upgrade rather than a format-warping answer here; Collector Ouphe is included mainly as a reasonable 2/2 for 2 that incidentally does nothing bad for us. Outland Liberator can answer a resolved Orcish Bowmasters-adjacent problem permanent or any enchantment like an Overlord of the Balemurk if needed, though its real utility is limited since they run few artifacts or enchantments worth destroying. The bigger threats are their efficient removal (Fatal Push, Solitude) and disruption (Thoughtseize), so we keep our proactive game plan mostly intact. This is a light, low-risk sideboard plan since few of our cards are dead and few of theirs are hit hard by what we have.
