This is the additional level 0 economy that Guardian has been wanting for ages. Worst case, you can probably find a 2 HP enemy to defeat, making this a fast 2 resources, which is slightly better than Emergency Cache which Guardians are usually forced to play. Often you'll be able to find a 3 HP enemy, or later in campaigns enemies with 4+ health, which makes this a total bonanza. And it has the bonus utility of being able to give the money to other players, if they have a use for it and you don't. Note that you don't necessarily need to be defeating the enemy yourself, the enemy just needs to be defeated at your location.

Another way to look at it: you can think of a deck in terms of what its interaction with enemies is:

1. You're good at fighting them. Enemies with 2+ health will be dying around you constantly, and with a little patience you'll see plenty of enemies dying with 3+ health.
2. You're good at evading or otherwise avoiding them. You may not see many enemies dying around you, so probably pass on Bounty, but you could still consider it.
3. You need someone else to help you with enemies. It'll depend on who else is in the team, but it's more likely that they're a fighter than an avoider, so you'll still see plenty of enemies dying.

Close to an auto-include in any Guardian; good enough for consideration in investigators that just have a Guardian splash.

Unusually, this card doesn't specify that the enemy be a non-weakness enemy. So would a weakness enemy get shuffled into the encounter deck? That feels weird, but it probably isn't too game-breaking at 3 resources. (And Alessandra still can't use it herself against Zamacona as it's a Parley action.)

Also, I really dislike card art in recent cycles. The "gang" in the card is about as unintimidating as it's possible to imagine. The scariest thing would be listening to them discuss the best way to make quinoa salad.

There is one campaign that threatens to make this card worth it.

Dream-Eaters has swarming enemies where 1 enemy counts as many. If you get a swarm with 2-3 monsters, you can make this card kinda worth it even in low player counts.

That said, I would still probably take Daring any day of the week over this.

A recent review of Darrell's Kodak reminded me of how insanely well this card synergizes with it. You are "very" (as odds come) likely to essentially get 1 evidence and 1 clue without spending an action. It's even better: You can both pick the best investigator suited for the drawn encounter card AND choose their location for discovering the clue, snatching the just-placed evidence.

That last part really makes me think they designed Nature of the Beast heavily with Darrell Simmons in mind.

Bandages probably does the job as well or better most of the time. You're paying 1 xp for an extra supply (fine, but probably not a priority). You can use this to heal damage that is in play before it comes out, which Bandages can't do, but this can only heal once per turn, and it can only heal yourself/your allies, where Bandages can heal other players and their allies. I could see upgrading Bandages into this late in a campaign when I'm out of other meaningful ways to spend XP, but otherwise I do not think this is likely to make it into my deck.
