I think this applies to a couple of cards, but the one that got me thinking about it is this:
Can you play the Single Purpose Command Card on Leia to re-use Battlefield Leadership to give away the other figure's attack, even though Leia herself would not be able to attack a second time? In a way, it strikes me as similar to Onar using "To the Limit" even though he's unable to become stunned.
I know that's fairly situational, but with the rebel meta increasingly looking for multiple attacks out of their solitary big hitters (Han, Chewie, Drokatta), it feels like a fun option. Three Shrapnel surges out of Drokatta, anyone?
I suppose other examples would be whether Jarrod can use Leaping Slash to jump two spaces (say, if his movement points were maxed out from holding crates on the Jabba mission), or the Nexu's Pounce ability.
