Is there something I am missing? Perhaps you're missing some of the previous Lost Legacy sets.
The "Whitegold Spire" set in particular utilizes a face-up/face-down mechanic.
Since LL decks can be combined, the "X" found in The Werewolf would interact well with those cards.
If you're not playing with combined decks, carry on as usual. You're correct, cards are typically discarded face-up.
