Can you discard a disabled upgrade?
If I have the Gavroche...
"Action: Disable up to 2 of your crew upgrades and add +1 attack die to each of your attacks this round for each crew upgrade you disabled with this action."
And my captain is Lore...
"During the Roll Attack Dice step of the Combat Phase, you may discard 1 of your crew upgrades to gain +1 attack die for that attack."
If I were to disable 2 of my crew upgrades to gain the attack bonus, could I then use Lores ability to discard said crew?
I know that you can't discard a disabled crew member as a part of his own ability... But this is slightly different as Lore is the one using the ability.
If something else is causing the discard, then, yes.
You can discard any card as a result of another discard effect unless the effect says otherwise.
You can't activate an ability on a card if that card is disabled.
You can't disable a card that is already disabled.
So Lore targeting a crewman disabled by the Gavroche is fair game.
