Esper GenericBlink leans on blink/flicker value engines like Phelia, Exuberant Shepherd, Flickerwisp, and Ephemerate reusing Solitude and Witch Enchanter's enter-the-battlefield triggers. Grafdigger's Cage stays in the sideboard: Flickerwisp, Phelia and Ephemerate all bring permanents back from exile, which Cage doesn't affect. Nature's Claim comes in instead because Overlord of the Balemurk is an enchantment creature, so it can be destroyed for one mana (its controller gains 4 life), including while it is sitting on the battlefield with time counters. Thought-Knot Seer strips a key piece like Thoughtseize or Solitude from their hand before they can deploy it, and Pithing Needle can shut down a problematic activated ability such as Emperor of Bones' adapt if one emerges. Blade of the Bloodchief, Vexing Bauble and the mana artifacts are cut since they contribute little against a deck full of efficient removal and card advantage like Overlord of the Balemurk.
