Buff strippers and buff thieves: The Defense buff and Immunity she gives herself are her main protection; an enemy who dispels or steals those buffs leaves her exposed right after she spends her whole Fighting Spirit gauge to gain them. Buff-duration shorteners: Cutting the length of her self-granted Defense and Immunity buffs erases her safety window before she can capitalize on it, wasting the resource she just consumed. Enemy Immunity and cleanse: Much of her pressure comes from landing the Defense-down on her basic and feeding her gauge through ally debuffs; opponents who run Immunity or cleanse those debuffs off blunt both her chip damage and her passive's fuel source. Burst before her ultimate is ready: Her team-wide debuff cleansing, Combat Readiness push, and Defense-penetrating area damage all live on a 5-turn cooldown skill, so aggressive teams that open hard can punish the turns where it is unavailable and she is leaning only on her single-target basic.

In current Champion+ RTA, Shepherd of the Dark Diene has one of the strongest records against Designer Lilibet (55% win rate over 4,739 games).

High-defense walls and tanky frontlines: Her ultimate ignores half the target's Defense and her basic can lower an enemy's Defense, so beefy bruisers and guardians who normally shrug off hits still take heavy damage from her Defense-scaling strikes. Debuff-heavy and damage-over-time teams: Her ultimate cuts 2 turns off every debuff on her allies and her passive lets her shed all her own debuffs when her gauge fills, so poison, burn, and stacking-ailment teams struggle to keep harmful effects sticking long enough to matter. Control and lockdown comps: By trimming debuff durations off the whole team and granting herself Immunity when her passive triggers, she lets her side wriggle out of stuns, silences, and slows that would otherwise pin them down. Slow, turn-starved enemies: She pushes her own and her allies' Combat Readiness (40% on herself from the passive, 15% to the team on the ultimate), letting her squad cycle turns faster and out-tempo opponents that rely on going first or getting extra actions.
