Add : the trick is make chaze have lot of health, chirrut must have high speed. His first turn, u do his tenacity up buff. It will not make plague dissapear, but tenacity up will prevent the plague spread. Also make sure chirrut have high crit chance, bcause when he crit he will spread heal over time to the team. Under cls he will counter a lot, and u have heal over time a lot also. It's better health regen than wedge lead health bonus regen.
U also can use rex to prevent plague spread, but his health pool is not much as chaze where both have health bonus from their unique. Rex will not stand long.
