Not very good. Most of the time you'd be better served just shooting again. If you really need bonus accuracy on an occasional key shot, include skills like Overpower or Adapt and Overcome or Armed to the Teeth instead for icons to commit. If you're scared of missing an attack and dealing damage to an ally, spend the action engaging the enemy instead.

Might be ok with "shotgun" style weapons (e.g. Winchester Model 12) but I'd usually rather pack my deck with static boosts, skills, and ammo reloads, and just shoot more often.

Evading an enemy can be nearly as good as defeating it, so against enemies that have a high combat stat but low health, this can be a way to get a low-difficulty test to deal with them. Also doesn't have the drawback of dealing damage to your teammate if you miss an attack while they are engaged, or damage to yourself if you miss an attack against an enemy with Retaliate. And getting a clue to boot is a nice bonus!

Also potentially handy against Aloof enemies, as you don't have to engage them first. Make the Whippoorwills sing a happy tune for once!

Note that this does not have a "non-elite" clause, so if you're able to crank your high enough or otherwise automatically succeed (e.g. Scrape By), you can use this to make anything, even a Great Old One, dance to your tune. Or rather, sing you a tune, I suppose :)

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.

Staple card for Guardians; 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.
