Resourceful is probably the best example of what secrecy could have been. An extremely versatile card that is bonkers good in secrecy, and relatively playable if not. Sadly, most secrecy cards are only worth it while you're under that ever-important twenty threat threshold. Still, an extra resource a round is undeniably good, so if you're planning to run the long game; Resourceful might be worth the deck space.
