Who Counters Monarch of the Sword Iseria in Epic Seven?

Lone Crescent Bellona, Swift Flagbearer Sigret, Arbiter Vildred and other hard counters counter Monarch of the Sword Iseria. Her whole identity is retaliation; an enemy that prevents or ignores counterattacks shuts off her doubled counters, the ally chain-counter, and her Sword of Duty conversion all at once.

Counter-blocking effects: Her whole identity is retaliation; an enemy that prevents or ignores counterattacks shuts off her doubled counters, the ally chain-counter, and her Sword of Duty conversion all at once. Dispels and buff-strippers: She relies on the attack-scaling barrier she grants herself after attacking; stripping that shield leaves her exposed, and removing her buffs undercuts her survivability between counters. Burst before she retaliates: Her damage is reactive, so a team that opens with a fast, hard strike can drop her or her front-liner before her counters and barrier come online. Cooldown and self-Fracture timing: Her team-wide hit, Dawnbreaker, sits on a 3-turn cooldown, and her big strikes self-inflict Fracture; opponents can play around the downtime and exploit the window where her own debuff is active.

In current Champion+ RTA, Arbiter Vildred has one of the strongest records against Monarch of the Sword Iseria (59% win rate over 9,422 games).

Teams that lean on hitting her: Her passive doubles her counterattack rate and drags the foremost ally into countering too, so any team that keeps attacking her gets punished with extra retaliation strikes that ignore Defense. High-defense and high-HP walls: Her counters and skills penetrate Defense, and her Injuries permanently cut a target's max HP, so beefy tanks and bruisers melt faster than their stats suggest the longer the fight runs. Slower compositions: Sword of Duty pushes Combat Readiness on herself and the foremost ally, letting her team grab extra turns and out-tempo opponents who don't move first. Debuff-stacking enemies: Dawnbreaker cleanses all debuffs off her before it strikes, so poison, control, and stacking-debuff strategies aimed at her get wiped clean on her turn while she still hits the whole enemy team.
