This card really intrigues me. I can't quite put my finger on it, but there's something about it that has me eagerly trying to make a deck with it. It further extends one of my favorite subtypes, the "Transaction" subtype, quite profoundly too. It has a slim window where it's ability can be used, but if you can use it, it's by far the best econ card in the game. On top of it costing 5 to trash and it being an upgrade, it's fantastic on paper.
The obvious synergies are with Closed Accounts and Reversed Accounts. There are other ways to make the runner lose credits, such as ice subroutines and overall just taxing the runner with heavy ice or forcing them to trash Mumbad Virtual Tour, but they aren't reliable and they can easily be played around. In a meta dominated by Şifr and Parasite, relying on ice to help you with a particular strategy is not something you want to do. You can always keep this card unrezzed and rez it when you want to use it. The runner most likely thinks you're not using this card. But with Hard-Hitting News being so popular, the runner is almost always above 8 credits. So this 'surprise' factory isn't reliable either.
Closed Accounts is the best credit denial card the corp has, but to get full use out of it WITH Bryan Stinson you need to use it as your first action so you can use as many transaction operations as possible before the runner gets 6 credits again, so that requires the runner float tags or somehow get tags on their last action, which is something that's not really done as running on their last action is dumb and there are increasingly better ways to deal with tags immediately, such as Aaron Marrón, and the overall amount of credits the runner has also makes tagging difficult. Tagging in Weiland is also challenging in itself to say the least. You can splash Hard-Hitting News and hope they can't remove all the tags, or splash the very expensive Midseason Replacements and hope you have the econ advantage to take full use of it. But if you're trying to make use of Bryan Stinson, you probably won't have the econ advantage. You can also use Bryan Stinson in NBN, but influence is rough, because you will probably want to use NBN: Controlling the Message to combat Parasite and Şifr. This means you will struggle to find influence to play the more important Weiland cards such as Scorched Earth and BOOM!, consdering Breaking News and SanSan City Grid are on the MWL.
Reversed Accounts is far easier in Weiland but more of a tempo hit and can easily fail. Weiland isn't known for their traps, so if the runner sees a card with advancement tokens on it they will probably have no fear running to access/trash it. If they do trash this card with advancement tokens on it, then that is probably an entire turn you just wasted.. which is not good to say the least. If the runner is also filthy rich, Reversed Accounts becomes increasingly bad in conjunction with Bryan Stinson. And the runner probably is rich, because of Şifr and Parasite, taxing ice means nothing.
Overall, this card is very interesting and when it's conditions are met it is the best econ card in the game. It's fun and extremely satisfying when you do pull it off, and of course very powerful. However, Bryan Stinson requires a fair amount of cards in conjunction with it to really make use of it, cards you might not otherwise use. So you're using a lot of your deck space for a wombo-combo that might or might not work. There are too many essential corp cards you would be missing out on if you use this combo. Not to mention, Weiland is also very weak at the moment. I think as the game goes on, this card can only get better.
