I wouldn't have believed it if I hadn't seen it with my own eyes… an encounter pack with a total of ZERO useable player cards, UNLESS you pigeonhole your deck to do what the designers want you to do. Wow am I disappointed. There have been efforts on the part of the designers in the past to stifle creativity and individual thought in the deck design process, but this is the worst offense.
It's more forgiveable in multi-player, but this pack just thumbs its nose at solo play, much the same way Secrecy did. A cycle of cards that require you to ignore all but one sphere is ridiculous. The only sphere that can do that and still have a chance of holding its own in solo play is Lore, and that would only work if you run three Song-searchers and the mana fixer cards. You'd still have to have things like Test of Will and Hasty Stroke if you want to pull out consistent victories.
If I hadn't wanted the adventure, I'd have just passed this pack right on by. Fail.
