Esper Control has a deep suite of counterspells like Counterspell, Spell Snare, and Consign to Memory plus sweepers in Supreme Verdict, so Exquisite Firecraft's cannot-be-countered clause is huge for pushing through the last points of damage. Rakdos Charm's discard mode strips a Teferi, Time Raveler or Supreme Verdict before it resolves, while its artifact/enchantment destruction can hit an Isochron Scepter engine. Skullcrack is both uncounterable reach and shuts off any incidental life gain from Solitude or Day's Undoing lines. Seal of Fire and Eidolon are weak since they're easily answered by removal-light but counter-heavy interaction, so proactive, resilient burn replaces them; sequence your threats to play around open mana for Counterspell and Spell Snare.
