I'm still waiting on my Stormtrooper zeta, having it land on his unique could turn his whole kit around. Something crazy like while Stormtrooper is taunting he has damage immunity, so he lasts his whole taunt. Or bump his defense bonus to 50% for each living Empire ally, and add revive chance equal to the defense bonus.
Imagine him literally unkillable till he's the last one on the field. Wouldn't even be that OP since you'd kill him long before his 3 turn taunt ends anyway and he won't revive with it.
