I've been testing this in Daisy Walker with good results. It acts as a second copy of her Tote Bag for consistency, with a few advantages:

• If I see this before the Tote Bag (I won't play both) then Tote Bag becomes basically a Guts or Perception without the card draw.
• It costs 1 more than Tote Bag, but it improves your action economy. It allows you to play something into a hand slot as an additional action, and then if it's a Tome Daisy can use her own ability to use its as an additional action.
• These extra hand slots don't have to hold Tomes, so you could play a Fingerprint Kit, Pocket Telescope, Scrying Mirror, The Chthonian Stone etc. (as examples) without spending a "real" action.

This one looked weak to me (away from Nathan* obviously) but slowly grows on me the more I look at it.

It's effect is essentially to turn 1 resource into one extra card but first you have to trigger it and it's clogging up your hand in the meantime.

Card draw is very scarce for Guardians and you might have plenty of resources later so that's a decent trade.

If you think of it as a 'cantrip' card that essentially thins your deck it's more appealing again.

What makes it really interesting through is the two books in the corner. Guardians don't get a lot of those and they add a lot of flexibility.

I'd really like to see this card get an xp version.

Very nice and interesting card. I expect Enchanted Bow to see more play with the inclusion of that permanent, as it will only take one hand slot. You can't do that with Ornate Bow. I think, I will even try that myself as Wendy Adams. As a dexterity character, If you care about your other hand slot (Lockpicks obviously), you can compare this setup with just Hyperphysical Shotcaster, which already uses only one hand slot. The first option has infinite ammo and is way cooler, but the second has more burst potential. If you are not the main damage dealer, maybe one attack per round is not that bad with the Enchanted Bow

Having a hand slot signature is tricky. Every class has things to do with the hands. Having a hand slot -weapon- signature is even trickier, because throughout a campaign, it’s eventually going to compete with two-handed or really good one-handed weapons. Daniela has a signature that plays really well with her initial ability… But can’t coexist with chainsaw or sledgehammer, the apex damage options in Survivor. Sure, you can run toolbelt, but that competes with old coat(1), which is four soak for one XP and an action. (Bandolier could help hold your weapons, but it can’t hold your signature; It also fights for the body slot, and Daniela can’t upgrade because she levels into survivor.)

Tinker solves this problem masterfully. It attaches to either the weapons or your wrench, whichever comes first. It cost zero XP, a single resource and no actions. Previously, the wrench was a last resort weapon (+2 to hit and two conditional damage is rapidly outpaced by other options). Now, you can use the wrench as flexibly as you always wanted: presumably to taunt Enemies off the cluever, Aloof 1HP enemies in zero actions.

Playing Miss Doyle with Charlie Kane in a Charlie Kane deck inspired by the mediocre film, Evan Almighty (https://www.imdb.com/title/tt0413099/) - This Charlie likes his animals, has a Rod of Animalism and Miss Doyle is perfect for him - two allies in play for the price of one ally slot three (or two with the Rod) resources and only one action... plenty of icons!

Miss doyle gives one wild icon, so +2 to any test, and with Hope, Zeal or Augur there is the double benefit that covers all skill tests other than will tests:

Hope gives you an evade at a base skill of 5... or gives you +2 to either intellect or strength Zeal gives you an attack at a base skill of 5... or gives you +2 to either intellect or agility Augur gives you an investigate at a base skill of 5 or gives you +2 to either strength or agility

So just with Miss Doyle and your free cat lieutenant in play, say Augur, you get to investigate at 7; strength test at 5, agility test at 5 or will test at 4 once per round.

All in, if you are playing a simple Charlie Kane deck for the icon boosts then once powered up Charlie usually gets one good skill test per turn, but with miss doyle in play as well as a few others, its probably two good skill tests, and that is before any shenanegans with automatic successes on offer. With the Rod of Animalism, those three fast cards (Hope, Zeal and Augur) become zero-cost as well (so long as you haven't played another creature that turn.) It's really helpful not to have the resource burden if you want to change cat lieutenant to take advantage of that auto success.

One slight Scarlet keys related semi-spoiler-related question...

If one of the cat-lieutenants (Hope, Zeal or Augur) end up as a "hollow", and Miss Doyle is later discarded, do they get removed from the hollows.

As i read it, being set aside as a hollow is an out of play area... but if Miss Doyle leaves play through normal means (is discarded probably through taking damage/horror) then you search for hope, zeal or augur from the hollows and set them aside out of play... ready to be brought back if Miss Doyle re-enters play?
