Lets compare this to Nisei MK II.

Viral Weaponization trashes the runner's grip, taxing them ~5 clicks. It also has the side benefit of disrupting their game plan. Nisei MK II, when used on a scoring server, would cost the runner a click and a massive amount of credits. It can also open a scoring window.

This card is the one-time program version of Desperado run economy.

Lets compare this card to Jackpot, a card with similar mechanics. At the start of each turn, you would place 1 credit on Jackpot, but can only retrieve them when you steal an agenda, (which may not even occur late in the game). Bankroll places a credit per successful run, and if we consider that as once per turn for an aggressive criminal, is similar to Jackpot in that regard. However, it also costs 1 credit install compared to Jackpot's 0.

Its credits can be pulled at any time, compared to Jackpot's only when an agenda is stolen, but occupies a memory unit in the meantime. However, Jackpot can be trashed if tagged.

In conclusion, its power level is about equal to Jackpot's, and should be considered in aggressive criminal decks with spare MUs.

Although Tycoon's stats and numbers are above average, they are no where near enough to warrant its negative ability.

Lets consider Demara as a comparison.

Stats: Install, Base Strength, Boost, Subroutines.

Demara, ~0, 1, 2:3, 2:2

Tycoon,,,,,,1, 1, 2:3, 1:2

So, in exchange for giving the corp +2 credits, you save ~1 credit.

In addition, Demara is more powerful due to additional draws being usable for their bypass ability instead of being dead draws, making it even better than Tycoon.

In conclusion, you should just get Demara instead of Tycoon.

Lets suppose you are a big rig shaper aiming for R&D lock with click compression, because that is the type of deck you would play Upya in.

Sure Gamble is a popular economic card, in that it provides a profit of 4 credits with a credit requirement most runners have or can comfortably click to. It provides its credits in a burst, providing you with more credits immediately.

Upya is essentially a run economy card, (save for the rare combo turn usage), that is only usable with click compression, (such as Magnum Opus or Professional Contacts).

If you run every 2 turns to compensate for multi-access runs, economic limits, and corp securing of R&D, you will gain 3 power counters in 6 turns. That means you gain 1 click every 2 turns, and with click compression making every click worth ~2 credits, amounts to about ~1 credit every turn, which is... actually an okay power level. In 6 turns it will even with Hedge Fund.

However, for this card to provide that benefit, you would need to have a click compression card and your breaker suite already installed, in addition to its memory requirement. You may also have difficulty in running on R&D.

Another comparison would be to Data Folding, which needs 2 free MU but does occupy them, and evens with Sure Gamble after 7 turns.

In terms of its numbers, Otoroshi has a gross tax of 6, (and a net tax of ~4), which are great in relation to its rez cost of 2. However, Its weakness lies in its subroutine, which the runner may allow to trigger.

Otoroshi can be placed on a remote server to threaten a flatline with Project Junebug or a rig wipe with Neurostasis if it is protecting an advanceable card, (making it ideal in a shell game glacier).

Otoroshi can also place advancement counters on cards that cannot normally be advanced, and can be combined with API-S Keeper Isobel to become an economic booster, making this ice very efficient and impactful.

Other synergies include Trick of Light for fast advance, Back Channels on an advanceable trap for an economic boost, and Constellation Protocol to support advanceable ice and Mass Commercialization.

If you find any other uses or synergies, mention them in the comments.
