Esper GenericBlink leans on Flickerwisp, Phelia, Exuberant Shepherd, and Ephemerate to reuse ETB effects from Solitude and Orcish Bowmasters; Grafdigger's Cage prevents creature cards from entering from the graveyard or library (relevant if they ever lean on recursion) and stops cast-from-graveyard tricks, though its main value here is simply a cheap, proactive artifact that doesn't interact with their blink engine directly, so treat it as a minor hedge. Wastescape Battlemage's blue kicker bounces a problematic creature they control, such as a blinked Solitude or Quantum Riddler, for a tempo swing. It can't target planeswalkers like Teferi, Time Raveler. Cut Nulldrifter, which is too clunky against their efficient removal and tempo plays, and trim one Sowing Mycospawn for the same reason.
