A hellova payoff for the Double or Nothing combo rogue build and what really helps make the deck super powerful late-game. For those that haven't tried it, the idea is to find a test that you can pass by a lot, and then throw out a ton of cards on the skill test such as Quick Thinking, "Watch this!", Gregory Gry bets, and potentially either versions of Deduction or Vicious Blow or a Fingerprint Kit or super attack from Timeworn Brand, boosting your stat further potentially with Streetwise or other various skill cards, and then using Double or Nothing to double all the bonuses you get from succeeding. This combo can already be absolutely nuts when it goes off, scooping up an entire location's worth of clues or 1-shotting all but the most bulky of enemies while also giving you 2 extra actions and a ton of resources. But that combo was somewhat limited by the fact that you could generally only do it at max twice in one scenario since you would have to go through your entire deck to be able to get more copies of Double or Nothing, and without a ton of card draw or assistance from allies it might be difficult to even assemble it more than once.
Enter All In, which can be tacked onto that whole combo to, in addition to ALL the other stuff you'd already be getting, draw you 10 cards with all weaknesses shuffled back into your deck. This is a godsend in several ways. Firstly, drawing 10 cards is absolutely nuts, even if you have to discard during Upkeep (And you often do) it's very helpful to restock your hand with helpful cards. Secondly, it will often either draw you into being able to perform another combo or will get you pretty close to being able to do one. Finally, it draws through your deck and lets you reshuffle all your key combo pieces back into your deck so you can draw and play them again. This means that with good draws and long scenarios it's not unfeasable to get 3 or potentially more full combos off each scenario.
If all of this sounds completely insane, it's because it is and is likely what led to Double or Nothing getting hit on the taboo list. Even with the XP hit I still think this is definitely a powerful and certainly extremely fun way of playing Rogue, and if you feel safe enough to run Charon's Obol or you got a Mystic or two running Delve Too Deep it's still totally worth springing for. For decks that aren't running Double or Nothing though I'm not sure if All In quite gets there. There's just so many insane cards to spend XP on for Rogues such as Ace in the Hole or The Gold Pocket Watch if you're playing with 2-4 players that dropping 10 XP for two copies of this feels kinda weak.
