peacekeeping (spender)
Spender barbarian-fort rally lead; also granted by the First Recharge Bonus offer.
Budget deputy option: Yoshitsune's cheap single-target nuke slots under Nevsky's cavalry buffs without changing the playstyle.
Two single-target cavalry nukers; Cao Cao's march speed delivers Yoshitsune's burst before the target can disengage.
Baibars' AoE slow holds a crowd in place for Yoshitsune's single-target execution.
Pelagius' cavalry skill kit backs Yoshitsune's nuke, and his post-rework S rating may lift this beyond a budget pick.
