Esper GenericBlink is a near-mirror where both decks leverage Ephemerate, Phelia, and Solitude, but they supplement with black cards like Thoughtseize, Overlord of the Balemurk, and Fatal Push. The key edge you have is Teferi, Time Raveler — it shuts off their ability to Ephemerate at instant speed, turning their interactive suite off and forcing them to fight fair. Consign to Memory answers their Overlord of the Balemurk (which would otherwise strip your hand), Emperor of Bones recursion, and can counter key Ephemerates on their Solitudes. Thoughtseize is their best card against you — prioritize protecting your Teferi and key threats through your blink effects. Your White Orchid Phantoms remain in the board for this one as the manabase disruption is less relevant; instead focus on tempo plays and outvalue them in the mid-game with Quantum Riddler card advantage.
