Esper Control wants to land Teferi, Time Raveler or a Wrath of the Skies while backed up by Counterspell and Orim's Chant, so Consign to Memory lets you fight through their countermagic at a mana cost they can't easily beat. Spell Pierce is strong on the play to blow out an early Teferi, Time Raveler or Wan Shi Tong before they untap. Tormod's Crypt is a low-cost way to strip Consult the Star Charts value or their own graveyard shenanigans. Cut low-impact cantrips like Mishra's Bauble and Boomerang Basics since they don't meaningfully progress your gameplan against a deck full of card advantage and sweepers; prioritize resolving and protecting one threat at a time.
