Magnificent. Introducing the Browning Automatic Rifle, a weapon that lets you spend exactly as much ammo as you need to one-shot the enemy.
I think the most obvious card to compare this to is Lightning Gun, and I think they tend to be neck-and-neck. The key here is that the Lightning Gun's insane +5 bonus is usually more than you need, given that every character who can buy this already has at least 4 . Mark Harrigan in particular is going to prefer the BAR's more judicious approach to spending ammunition.
Some noteworthy interactions:
- Probably the best card to date to combine with Sleight of Hand, so Zoey Samaras and Leo Anderson should especially consider it.
- One of the few cards for which Contraband unambiguously pulls ahead of Extra Ammunition.
- Speaking of which, Extra Ammunition and BAR are genuinely terrible together. You want Extra Ammunition to at least double your usage out of a weapon, and this combination is nowhere close. (I might consider it before Contraband, though. You could probably make the case that it's worthwhile to get 22 ammo instead of 16.)
The BAR seems to just generally love Rogue cards, actually. Even Double or Nothing, a card I'm not ordinarily fond of, can seriously up its game in a BAR deck, where its chances of producing a 10-damage strike are much better than with Shotgun.
In all, the Extra Ammunition problem prevents the BAR from being quite as good as the Lightning Gun, but it's not quite as expensive, either, so they're roughly in the same tier. (Lightning Gun pulls ahead on Expert, though, because its +5 becomes more relevant.)
The BAR seems so powerful for Leo that I think it's my automatic first upgrade if I ever run him.
