Okay, I did not quite expect this entry to be about what it ended up being. So Pete Lanning...

To begin with, I honestly liked the background of this NPC a great deal! Might just be me being fan of the Spirit Playbook's concept, but fairytale encounters are something I can only approve of. The Deck's gimmick is also very neat, and carries that Fey sense of whimsy and capriciousness to it. Admittedly I'm not all that familiar with Peter Pan beyond basic cultural osmosis, so a lot of the nuance and references are definitely lost to me in way where I can't fully appreciate the work put to this.

One thing, though, that I wonder is if the deck does use {Fumble} a bit too much, particularly if you have Isle of the Lost and David out at the same time? With Advantage besides starting points and {Ace}s being ultimately luck-based to generate, and most often it taking one point to work against each {Fumble}, it can become more frustrasting than challenging to deal with constantly if you don't come to the game with a fair bit of Baggage?

Still, good job!

Nice, simple, and thematic deck with a neat mechanic/keyword attached to it. I like it. Good job. :)
