I'm working on a rich over succeed Tony Morgan combat build that wants to use this as one of the primary weapons. Sawed-Off Shotgun will make it's way in too as it also wants to over succeed. Hard Knocks will probably be a huge get in this deck as well.

A couple of nifty combos in the deck around this card:

1. Overcommit with Momentum since you're trying to succeed by the fight value of a monster at your location this will make the next attack much easier.
2. Watch This, the extra money will be poured into hard knocks when you need some extra double taps.

Some core cards and why you'd choose them:

1. Opportunist & Opportunist - Generally good in over succeed but since you often will want to over succeed by a lot it's useful here.
2. Tabboo'd Sleight of Hand works with this gun.
3. Narrow Escape helps when you need to play a new gun after picking one up with Well-Maintained. The +2 on your next shot is welcome for mowing down 2 enemies in one check.
4. Daring Maneuver is probably gonna pull some weight in terms of adding consistency to your double taps.
5. Since you're already going for oversucceed pair your main gun with some Mauser C96's to get some added resource generation when doing normal fights and Switchblade to round things off.
6. The upgraded Joey "The Rat" Vigil will be a great way to clear your cheaper weapons and make some money for your main one and let you compress actions in general since you're already money focused.
7. With Contraband (and Contraband) both in class and this weapon being an ammo hog it might be worth it to run.
8. Decorated Skull & Decorated Skull probably work ok here as you're a primary fighter and when You're not fighting you need to be preparing while sitting on top of your clue gatherer.
9. "Let God sort them out..." might actually work in this deck, probably as a 1 of, as you will have the kill potential and action efficency for offing 6 dmg worth of enemies when combing across multiple enemies.

I'm not sure yet if the deck is going to be great but looking at this card I do feel like it has potential, especially in campaigns with lots of enemies like Dream-Eaters. I feel it particuarly pairs well with evasion heavy investigators such as Trish Scarboroughor Ursula Downs.

This is great in a draw heavy Mark Harrington deck. You're able to constantly use your self dmg for +2 ability and continually reap the heal from this. It's built in draw + your ability to to draw in several rounds makes this a priority upgrade for Mark when I play. It might even be the only heal he needs when paired with some soak from allies. I used to spend 5 xp on Spirtual Guidance as an early priority but that xp might be better used on earlier guns now.

This is a spectacular card for Calvin. +2 to all stats and an extra action to boot, and he can get enough resources to fuel it with Drawing Thin and a small loan. There's the small problem that he can't actually include the card in his deck, but just Teamwork it to him and Bob's your uncle.

For actual rogues, I'm not the biggest fan. It works in exactly one type of deck: big money rogues. Even in such a deck it's a luxury purchase that takes at least a few turns to come online. You can always grow an extra neck to hang your clock on but you can't buy extra hands, and for most rogues those hand slots are somewhat important. However, for Sefina and Preston Fairmont, rich folk who's hands are often idle and who's never done a honest day's work, the Black Fan is an excellent capstone to their builds.

While this card fits well with the seeker from the same expansion (and by “seeker” I mean Monterey Jack, since he’s the one who can take the upgrades, plus he will be moving around all the time), it is an even better fit with Ursula Downs. I think the synergy is simply perfect, since the Archive encourages you to move and successfully investigate once a turn. And what does Ursula do? She gets a actionless investigate after moving, once a turn. Not every scenario will have 4 locations in play during the first or sometimes even second act. By the time the necessary number of locations are put into play, the clues on the initial locations will be gone, and you would not want to return there to investigate empty locations. Since the Archive is only 1 per deck, you may not find it quickly enough, before the Mythos starts putting the real pressure on you. Ursula’s free investigate helps you ease out the pain in all of the above situations.

I see good synergy with Bob Jenkins. Somebody else plays Bob who then plays your items (or somebody elses) and Charles pays for the stuff.

Take him yourself using 1 / 2 Versatile do get some other class items and more rogue-zeros. Or let somebody else take Charles Ross, Esq..
