Esper GenericBlink is a mirror-style matchup built around similar blink and value creatures like Phelia, Exuberant Shepherd and Overlord of the Balemurk, so efficient bodies and free interaction matter most. White Orchid Phantom is a flying, first-strike blocker that can also strip a key nonbasic land, giving you a proactive threat that dodges their ground creatures and disrupts their manabase. Force of Negation gives free interaction on their turn to counter a critical noncreature spell like Teferi, Time Raveler or a key Ephemerate. Trim Faithful Mending and Persist since this matchup favors efficient bodies and free counters over grindy card selection against an opponent running a very similar plan.
