Who Counters Sinful Angelica in Epic Seven?

Perfumer Byblis, Shepherd of the Dark Diene, Frieren and other hard counters counter Sinful Angelica. Almost everything she does runs through her own Immortality and the team Attack buff; an enemy that dispels or steals those buffs strips her safety and her offensive payoff in a single action.

Buff removal and stealing: Almost everything she does runs through her own Immortality and the team Attack buff; an enemy that dispels or steals those buffs strips her safety and her offensive payoff in a single action. Cleanse and shortening buff durations: Cleansing her Immortality, or cutting its 2-turn window short, drops her out of the immortal state that gates her Dual Attack trigger and keeps her from leaning on it to survive. Effect immunity on the target: Her offense relies on the Decrease Defense chance landing; an enemy under immunity shrugs that off, and it also blocks the anti-revive lock she wants to apply. Unhealable application and slow cooldown: Her team sustain is the on-death heal from her passive, so making her allies unhealable neuters it, and her cleanse-plus-immortality button only comes back every 5 turns, leaving long gaps where she has no protection to offer.

Teams that lean on reviving a fallen carry: Her passive flatly stops enemies from coming back, so a comp that wants to resurrect its key hero loses that safety net, and each enemy death instead feeds her team a heal scaled off that target's max Health. Heavy debuff and damage-over-time pressure: Her 5-turn skill dispels two debuffs from every ally at once, so stacked control, poison, bleed, and other lingering damage gets scrubbed off the whole team in one move rather than ticking down a carry. Enemies that try to lock her down or pick her off: She grants herself Immortality for 2 turns, so attempts to burst or stun her into uselessness fail while it holds, and that same immortal window powers her bonus Dual Attack to keep pressure up. Defensive, tanky opponents: Her staff hit can drop one target's Defense and she buffs all allies' Attack, softening a durable enemy so her damage dealers punch through it.
