Used Vault Salesman!

Short version:

It's the Vault + Recall engine WITHOUT oaktown.

Vault + recall = 0 cost gain 4 (net 8 for 2 cards).

Vault + recall + oaktown = 1 cost gain 3.6ish (net 10 for 3 cards).

Oaktown only makes you money if you can keep it protected for more than one firing of the combo, and in the meantime takes up deckspace for a card that just isn't good for anything else. Vault and recall aren't good for anything else either, but a 2 card combo is much better than a 3 card and I need to protect it combo.

I threw this together quickly and have done way better than I thought, but it was sort of a "lets test a few ideas" deck, hence the oddness of the build, but I think there's some merit here and highly recommend tweaking. Vault+recall might just barely be legit.

Anyways some card specific breakdowns:

Sealed vault/Product Recall-

The upside is it's a somewhat safe way to run 6 more hedge funds. The downside is that they serve no other purpose and you do require the other half of the combo to do anything with them.

Advanced Assembly Lines-

Mostly so you can fire ETF on their turn and get more triggers, but also to help spread the clicks on the combo a bit better while still making you money. Probably not needed (but hey the goal is to have all the plastic tokens).

ALL the recursion-

As I said initially I was just trying to kill 2 birds with one stone and test a couple of HB ideas. In practice though since you can quickly turn the recursion into money it has some merit? Probably not "6 operations, 3 agenda's, 3 influence eating ice, and the usual jacksons" worth of merit, but still. It is worth mentioning that getting a 1 or 2 counter vitruvius is very very worth it in this deck, especially if you have an assembly line ready to fire. Also it's fun to piss off the noise player for once.

Corporate Troubleshooter-

He's still probably terrible, but I do happen to run enough recursion to fire him Every. Single. Run. with an econ engine that does let you drop double digit credit amounts into him. Probably still not worth it, but can lead to surprise "i win" scenarios.

NEXT Ice-

Needed cheap ice. Decided since i'm running troubleshooter having access to gold would be worth it along with the other troubleshooter combo ice. Could probably ditch the whole package for the usual engima's and friends.

Upayoga-

Another "i've been meaning to test this" case. Obviously it competes with lotus field, which is a major issue. However given that this is a deck that can afford to throw money at it, I think the card is criminally underrated.

Short version is that the matrix looks like it's only "play 0/1" for optimal credit swing, there are scenarios where that matrix doesn't matter. Mainly if you can afford to just lose 4 credits, you can FORCE the runner to lose 4 credits (obviously assuming it fires), which can easily lead to Ash lockouts or problems breaking other ICE. Always check if forcing the runner to lose 4 will push them past an important threshold before playing the game, and if it will, just bet 2 both times. If it won't, only bet 1 or 0.
