Wow, these aren't disappointing. Each challenge deck is changing the rules in its own way. I like what they've done here, essentially turning the tables and forcing the dark side on the offence. The pyramid of objectives is also a neat touch.
Although...if the LS win condition is to deck their opponents, is this challenge deck going to impose a deck limit for the dark side?
I'm hoping standard decks will be playable against the challenges. The last thing I want for this game is a repeat of the LotR LCG, where players are expected to tailor decks specifically to each challenge. (Although I suppose it would be less of an annoyance where deck construction is a quick affair.)
