Jyn Erso

To resolve this card’s effect, you must discard a [squadron] dial or a [squadron] token (your choice), then also discard this upgrade card regardless of if you discarded a dial or token.

Reference

Can you discard cards in multiple upgrade slot? (i.e. Can Sunder, Shriv, or Boarding Vader discard Boarding Troopers, etc.?)

Karneck: My conclusion is they can, based on the consideration that the upgrade card is a single card that requires both upgrade card slots, but is considered to occupy each slot when checked.

Brooks: Shriv (or Sunder) can discard any card with any of the listed icons, regardless of any other icons it might have. The word “or” is used to make it clear that only one card can be discarded, not one matching each icon. Upgrade icons are properties that upgrade cards possess, and which are sometimes used to refer to them, but the rules have never distinguished a “Weapons Team + Offensive Retrofit” card from another card with only one of those icons for any game mechanical purpose.

When a ship equipped with Jyn Erso reveals a command, it disgards that card and either a Squadron dial or token to choose 1 enemy ship at close range.
If the chosen ship has no raid tokens, it gains 2 raid tokens of your choice, also, if that ship has an objective token, you may gain a victory token.

If you gain a victory token but the objective being played has no victory points associated with that victory token, then that victory token is worth 0 points.
