Just to be sure :
Can i use this reaction : "After you commit a [Sith] unit to the Force, place 1 focus token on a target enemy unit." after attaching Mara Jade's Lightsaber to Mara Jade?
Second question :
Are units considered committed to the force "immune" to effects like this one? : Reaction: After you win a Force struggle, destroy all units not committed to the Force.
Thanks for the answer.
