Who Counters Assassin Coli in Epic Seven?

Lady of the Scales, Swift Flagbearer Sigret, Witch of the Mere Tenebria and other hard counters counter Assassin Coli. Her self Attack and Stealth only trigger while she is clean of any debuff, so even a minor debuff stuck on her shuts down her engine.

Debuff application: Her self Attack and Stealth only trigger while she is clean of any debuff, so even a minor debuff stuck on her shuts down her engine. Cleanse and immunity: Her one piece of control is the kill-conditional team silence; teams that strip it off or pre-shield with immunity simply ignore her lockdown. Surviving the strike: She is single-target with no area damage, and her silence only fires if Murder actually defeats the target, so a tanky or healed-up foe she can't kill leaves her control on a long cooldown with nothing to show. Buff removal and shortening: Her own Attack, Speed, and Stealth buffs can be stolen, dispelled, or cut short, stripping the stealth bonus damage and Speed she needs to function.

Skill-cooldown reliant enemies: If Murder secures a kill it silences the entire enemy team for a turn, locking opponents who depend on landing a specific active skill out of casting it on their next turn. Fragile, low-defense targets: She is a single-target finisher whose damage climbs with her own Speed, and Ambush from stealth hits even harder, letting her delete a squishy backline pick before it acts. Slower lineups: She runs very fast, builds her own Speed, and gains more Speed out of stealth, so she takes turns first and can act before opponents set up.
