After a campaign with this in Winnifred I think the card can be a pretty nice addition to a Taboo'd Rogue deck in 3-4 player games assuming you're going to be doing evading with any amount of frequency. Extra actions with low cost are always worth considering, and in the right situation this can save you up to 3 for just the cost of committing a card to a test. While you don't get free reign on what those actions are spent on, move actions are fairly commonplace and if you have this card in your hand for a full scenario there's definitely going to be some situations where it'll do its baseline effect and save you one move action that you were going to spend after evading. In those situations I'd argue that this card is already pretty good. And there'll be some situations where it'll save you 2 or 3 actions, in which case this card is incredible.
Now the effect isn't universally great and there'll be some situations where it'll spend half the scenario sitting in your hand before you get value out of it. As such, I think this is a card I would generally not run more than 1 copy of because drawing 2 when you really don't need the effect can slow you down a bit. But if you're someone who expects to be testing Agility a lot and especially if you're playing with 3-4 players where being able to move to an ally's location has a lot of value, I think you should try running a copy.
Also just want to say that while Quick Thinking is going to generally be better than Nimble, it's one of the best Rouge cards in the game and you're only allowed to run 2 copies of each card. I think there's a lot of decks that are interested in a more situational Quick Thinking-type effect to run in addition to the two copies of Quick Thinking they already have.
