Wow! In the class of extra actions and big money plays, we have a new Level 0 king!

This card nets 6 resources for 2 actions and 1 card. For multiplayer, this is better than Stand Together if your team needs resources more than you. With support this card becomes even better; Underworld Market to consistently draw this card early, Fence to reduce the action cost, possibly the resource cost too. Cards that gain additional actions are great here. Play this with Double, Double at your own risk. Without additional actions, this will eat your turn, but for 12 resources that may be worth it.

The obvious comparison in Rogue will be to Faustian Bargain, which nets 5 resources for 1 action, 1 card and 2 curse tokens. This is better if you are leaning in to a curse related theme, otherwise the curse tokens will cause grief for you or your team, especially if you use any "succeed by" cards, such as Lucky Cigarette Case or Quick Thinking. Hot Streak & Hot Streak can replace this at the cost of XP and a higher initial resource cost.

In a 3 or 4 player game, this card is great!

I really like this card. I view it as a "buy one preposterous sketches, get one free". While 5 is not double 3, you should take into account the fact that in each case you are spending 1 card to do this. Better yet, you can share those cards with your team. The cost savings is great since you'll probably want to be playing all those cards you just drew.

Thorough Inquiry: 2r, 2a -> net +4 cards

Preposterous Sketches: 2r, 1a -> net +2 cards

There are other draw events that save you resources but they either cost XP or add curses:

Deep Knowledge: 0r, 1a -> net +2 cards + 2 curses

Cryptic Research: 0r, 0a, 4xp -> net +2 cards

Preposterous Sketches: 0r, 1a, 2xp -> net +2 cards

See that triggered free action? THIS is what I'd love to see on a pair of 1XP Handcuffs in the future. Lemme reuse my cuffs... Come on FFG, please let us get reusable handcuffs one day. I don't want to try somehow get recursion or scavenge into my guardian decks. I just wanna be able to cuff more than 2 enemies per draw through of my deck.

Just wanted to point out that because Uncanny Growth is an Insight, it works very well with Crafty, which is already one of the best tri-class talents from EotE. With an upgraded Myconid it is almost pure upside (discounting situations where you cannot or are punished for playing events) as you can make Uncanny Growth free with 1 resource then test at +1 with the other.

Fits very nicely into the Ice Pick-Scavenging loop and other Insight-heavy decks (e.g. Joe Diamond). Big hand Seekers may also want to get into horticulture, especially Harvey Walters who can easily use Farsight on Uncanny Growth and would appreciate Nurturing Strain's soak for damage from his weakness and horror from deck reshuffling.

When I first read this card, I thought, "wow" eight resources!" and slotted it into my Alessandra deck. Two actions and six resource gain makes this equivalent to two emergency caches in one card! In reality, it just feels too clunky. Two actions is a lot of time, and other econ cards, like Faustian Bargain and Easy Mark put Bank Job to shame.

That being said, this does have a good home in a few decks. The first is big money, where it could be a nice shot in the arm and a placeholder for Unscrupulous Loan. It's too bad Preston can't take this.

The second, and more interesting home, is in the Underworld Market. One of the drawbacks of the Underworld Market is the resource cost, and Bank Job is a great way to afford it.

Lastly, It's nice in investigators who can take a lot of actions, though those actions are usually better used for basic actions like moving, investigating, and fighting.

Overall, this card looks better than it reads. It's good those who need a lot of money, but there are several more flexible options.
