Esper GenericBlink leans on Solitude, Flickerwisp, and Phelia's blink triggers plus Orcish Bowmasters' triggered ability, and Consign to Memory is well-positioned to counter those triggered abilities for a single mana, denying value from the enters-the-battlefield triggers they rebuy with Ephemerate and from Solitude's exile effect. Mystical Dispute is cheap and efficient against their blue spells like Quantum Riddler and Teferi, Time Raveler, since its cost reduction lets it counter them unless they pay {3} for just {U}. Mutagenic Growth is weak against a deck with free interaction (Solitude evoke) and cheap removal like Fatal Push that can simply remove the creature before combat anyway, and one extra Mishra's Bauble matters less than disruption in this grindy value matchup. Prioritize applying pressure early since their deck wants to go long with Overlord of the Balemurk and recursive threats.
