Rank Up Crit Burst
6★Spirit · Mental DMG · Rank Up + Crit — Ultimate dispels enemy buffs, grants party Crit Rate and 【Rank Up】 to the whole team, Euphoria (E1) required.
6★Plant · Reality DMG · Crit + self-dispel — Ultimate self-buffs +30% Crit Rate/+30% penetration on the same hit, second skill dispels the target's buffs first, Euphoria (E1) required.
6★Plant · Mental DMG · Moxie + self-sustaining AoE — 500% board-wide Ultimate fed by her own 【Hiss!】 card engine, Euphoria (E1) required.
5★Star · Sturdy + Heal + Shield + Moxie — keeps the three offense-first kits alive long enough for the Rank Up/Crit burst to land.
Mercuria's Ultimate is the only kit in the roster confirmed to grant 【Rank Up】 to the whole team, and the same cast dispels enemy buffs while stacking party-wide Crit Rate — both feed straight into Argus, whose passive already locks in a guaranteed Crit and whose own second skill dispels the target's buffs independently, so the two dispels rarely whiff. Hissabeth adds a second wide Mental nuke that runs almost entirely off her own card engine, needing nothing from the other three to keep firing. Yenisei keeps all three offense-first kits alive long enough to land their bursts.
