Lightning Bolt stays in. It hits any target, so it can kill Solitude and also pressure Narset and Teferi, which are among the opponent's best cards. Esper Control has few creatures, so the swap is small. Dreams of Steel and Oil takes a key artifact or creature, such as Solitude, from their hand and also exiles a chosen artifact or creature card from their graveyard. Street Wraith is the clunkiest card in the matchup. Its swampwalk is almost never relevant, and its five-mana body is weak against their sweepers, so it makes room for Dreams. Keep Thoughtseize active to strip their sweepers (Supreme Verdict, Wrath of the Skies) before they can wipe your board.
