This is the worst runner ID. Period. The only buff TheBigBoy was able to give him was +1 . Any other buff will make him broken. Making cards designed for him will likely be crappy or will make Leela Patel: Trained Pragmatist overpowered. Altering his minimum deck size to 40 is just ridiculous, as well as giving him 17 or more influence.
Why is he junk?
His ability is a red herring (No, not that card)
Fisk's ability is making R&D smaller and is flooding the corp, but the odds of them drawing Scorched Earth or economy cards is just too much of an advantage against you. To make his ability good, you have to first make the corp broke so they can't afford to play or rez the cards, forcing them to trash them at the end of the turn. Who knows? maybe they'll draw an agenda. Most of the time they'll score it so you're just giving them more points.
Making the corp draw cards: All or nothing
Making them draw just 1 card isn't always very good. You have to make them draw a lot with the aid of Eden Shard or Fisk Investment Seminar. there are other cards that help too, such as Woman in the Red Dress, but most are not efficient enough or are limit 1 per deck. What corp will choose to draw the card from WITRD unless they actually want it? FIS used to be limit 3 per deck, but then everyone would just use it with Leela.
He is the poorest criminal
He's supposed to be one of the richest men in the world, even owning his own corp, but he's broke almost all the time in the game. The reason why is because his ability doesn't give you any credits. Andy and Geist can draw money, Gabe, Ken, and Ian have money as an ability; Leela doesn't have money either, but her ability can slow down the corp. Silhouette is broke as well as Fisk.
Since has weak card draw, it's difficult for Fisk to draw enough money. Expect him to be broke and have a hard time.
How can he be good?
Well, there's more bad to him than good. You don't get the benefits of other IDs like Gabe, Andy or Ken, but his ability can be useful under certain conditions.
1: When the corp is broke. This is just half of the good use of this ID. He can flood the corp with tons of agendas and other stuff that they can't afford. it'll just go in archives. Think of his ability as "Noise but you might access it while using Lamprey". You can also use his ability to increase accesses from HQ if the number of cards you access is greater than the number of cards that are actually in their hand. even though this is rare, it'll be helpful when it does happen.
2: Make the corp draw scorch when their rich. This is the best part of this ID. not only do they have fun for once, but now this torturous game is over. It also makes the stats more accurate for the Reboot ranked board.
So, how do you use Fisk?
Siphon Spam
This concept is the best type of deck to use with Fisk (according to some sources). You play Siphon over and over again and use Same Old Thing to recur them. Not only are you rich, but you're also making the corp broke, making your ability worthwhile.
Any other concepts are utter jank a majority of the time, such as my deck: nrdb.reteki.fun
(Yes, Siphon Spam is the only good Fisk deck as far as my knowledge.)
Final Thoughts
I think the only ID that is similar in quality is Silhouette. Even she is better than Fisk. I think Fisk is the crappiest ID ever made. He shouldn't be good because his ability is just gross.
My Rating: 3/10. I think he's tier 5.
