GK and JMK

Mandalor

So GK can taunt, even he has breach, isolate or ipd use his special.
How's that's possible?

KausDebonair

JMK’s leader ability gives him taunt. The specific line “when they lose taunt they gain it…” The same goes for other units that have the “lose taunt gain taunt” mechanic in their kit. Old Ben comes to mind. Bossk, I believe, as well. That mechanic supersedes the other stuff.

TargetEadu

He’s essentially getting his taunt dispelled -> immediately gaining it back -> getting inflicted with Taunt/Buff Immunity/Isolate/whatever.
