I have a question about savage mana the card states whenever haka destroys a TARGET you put it under this card does that mean that if haka killed the Opetative that she would go under savage mana and if so would that mean that the chairman would not receive the damage boost she gives when incapacitated since she is no longer in the game?
No, because the operative isn't destroyed. She flips instead. Same as with Baron Blade. You could Savage Mana the Chairman or Omnitron as they don't have that benefit, though.
Ok that makes sense. If I savage manad omnitron would instill have to destroy his drones of there were some in play still?
Yup. Just as if you'd 'killed ' him normally
