So my initial thoughts. Lets have a conversation (and tell me where your opinion is different).
Trench Knife: Feel similar to how I feel about Blackjack. The lack of damage bonus makes it a no go in my book. I could see some uses for the special ability of not taking OOO from engage actions, but it would be pretty rare and would need some cards that synergize with it that don't exist yet.
Ambush: I like this card a lot. Better in a 3 or 4 than a 1 or 2, but a good, solid card. Cheap on the XP to.
Charles Ross Esq: Trying to get my head around this guy. He is basically one free resource a turn, for items only but you can use it on other players. Frankly Milan and his 4 resource cost has been grating on me lately and I am looking for alternatives. I am thinking Roland may like this guy. Jenny may become an all star with him.
Forewarned: This one is just very good.
Dario: He seems okay. He is pretty pricey, but a bonus to two skills is pretty nice. Skids, Jenny and Lola could use that.
Sneak Attack (2): Its definitely better than the level 0 version. I am not 100% sure that I would spend xp on it with other options, but I suspect the Rogue in my game will drop it in his deck pretty quickly.
Storm of Spirits: This is probably the best card in the pack. (Forewarned and test of Will may be better but no one remembers things that you cancel before it goes on the board.) Again probable better in a high player count game.
Book of Shadows: For most characters, this would just be a path to the level 3 version of the card and its kind of meh like the l3 version. With Daisy, this card gets a lot more impressive. I can really start building an effective Daisy caster deck with a number of the low cost mystic cards from this cycle while relying on her 5 Lore (with minor bonuses) to grab clues.
Fight or Flight: A good, solid card. Not sure where I would put it, but looks solid. Cards that can boost fight or evade are pretty effective. The lack of skill icons is notable. (I believe the only others are Lucky and Emergency Cache).
A Test of Will: Probably my favorite Exile card to date.
Devil's Luck: Okay maybe this one is my favorite exile card.
Calling in Favors: If I ever get around to making an Ally deck, this will be there.
