Esper Blink leans on cheap removal like Fatal Push and disruption like Thoughtseize alongside flicker value creatures like Phelia, Exuberant Shepherd and Witch Enchanter, so your own Thoughtseize helps you strip a key piece like Solitude or an Overlord of the Balemurk before it generates value. Prismatic Ending is only as good as the colors you can spend on it: with two colors of mana it exiles a mana value 2 permanent like Phelia or Orcish Bowmasters, but Flickerwisp has mana value 3 and needs three colors, so don't expect it to be a cheap one-mana answer. Goblin Bombardment is a weaker inclusion since their low-toughness creatures often die to combat anyway and you'd rather hold sacrifice fodder for Yawgmoth's card draw engine against their removal-heavy disruption suite. Watch out for their own Orcish Bowmasters punishing extra card draw.
