So my opponent picked up all 3 legacy cures on Immortal Hulk and it caused a bit of dust up. The cures crisis card says it KO's the person holding it. They were rather insistent that immortality would prevent him from being removed because he didn't currently have an immortality token, and that it would instead daze him and trigger immortality? Am I correct in assuming that the KO would bypass that rule since it never reduces him to zero stamina and doesn't care if your healthy or injured?
