Esper Blink relies on ephemeral value creatures like Flickerwisp, Phelia, Exuberant Shepherd, and Witch Enchanter, plus Overlord of the Balemurk and Solitude for card advantage and removal. Wasteland Strangler gives you a proactive threat that can shrink one of their key blockers or attackers by -3/-3 when it enters if you put an opponent's card from exile into their graveyard, which is relevant against Phelia or Flickerwisp. Dreams of Steel and Oil is a discard spell that also strips a card from their graveyard, hitting their Overlord of the Balemurk or a stranded Flickerwisp in one shot. Mishra's Bauble and Pithing Needle are fairly low-impact against their resilient value engine since they don't have a critical activated ability to lock down. Your discard suite (Thoughtseize, Inquisition of Kozilek) remains excellent at stripping their key enablers before they can chain value.
