Seems odd at first glance, why would you need +2 if you have passed? My initial reaction was that it would help land Double or Nothing but it doesn't actually help there, because of how that works (it doubles the difficulty rather than you needing to get double the target).

It does combo with cards where you need to succeed by a certain amount:

Switchblade

.41 Derringer

Opportunist (though this seems a pretty poor use)

Scavenging

Rex Murphy's trigger

Expose Weakness

Deduction

Alchemical Transmutation

(I might well have missed a couple)

Ultimately none of these uses are that mind blowing. I think a card that only works in combination, and only provides lukewarm benefits even if you draw the combo together is pretty weak.

Lists of cards that work with Daring Maneuver:

• "Succeed by", this is the main list.
• "Succeeds by" (currently only Deduction, Fearless and Vicious Blow).
• "Succeed at a skill test by" (currently only Lucky Cigarette Case and Rex Murphy).
• "Investigate by" (currently only Scavenging).

Daring Maneuver’s stock is going up as the succeed by X archetype is getting more defined. Momentum in particular works really well with Daring Maneuver, allowing you to turn any success into at least a -2 difficulty on the next test, which in turn can further enable more oversuccess. Tony Morgan with fight tests, "Skids" O'Toole, Wendy Adams and Finn Edwards with Lockpicks or Slip Away, Sefina Rousseau with Suggestion, or Jenny Barnes or even Preston Fairmont with Well Connected. Although the interaction with Lucky Cigarette Case is clear, this also works well with Crystallizer of Dreams as a way to be up 1 on a later test. I’m starting to run this card in most of my Rogue decks to good success.
