What a loaded card!
One of the main issue the basic version of "Watch this!" had was that it was only worth using on skill checks you were likely to pass, which for most Rogues would be only Agility, as it is their usual best stat, while their second best, Intellect, cannot benefit from the basic skill card in normal circumstances, lacking the matching icon.
Enter the level 3 version of the card , which simply converts all of the skill icons into wilds, that can be commited to any skill check!
That makes the card ludicrously easy to use, and makes it easier to fulfill the clause to get cash from it, as you can commit it to whatever trivial skill check you run accross
But what is great about this is that it turns "Watch This!" from exclusively a utility/economy card to a mix between utility, economy AND defense, as the three wilds are immensely more helpful to deal with treacheries than the lone Will pip of the basic version.
This gives the card amazing versatility: if you don't care about money, you can just use this to save your butt against a bad treachery that would punish you badly for failing its test!
Some people compare it as being an overpriced upgrade to Unexpected Courage, and I couldn't disagree more: the combination of both its resource genration and skill bonus, makes this much, much more versatile than UC, and far easier to slot in and use in many situations. You sometimes have to choose between skill cards that either give you strong effects (like Vicious Blow) and cards that provide high skill bonus for a number of situations (like Survey the Area) but "Watch this!" does BOTH at once, which is far more value than what most skills have to offer, and its versatility makes it that much easier to cut down the need to run similiar cards to fulfill different functions. It makes your deck more compact by combining multiple uses of different skills into one card and give you the option to replace overlapping skills with something different.
That is without considering the great synergy it has with other Rogue cards, and the "overachiever" archetype: it can help you reach a high result to trivialise your next test with Momentum, give you 3 wilds you can look for with either Daredevil (a card which really likes finding wilds that are eligible to any test) and make it more likely for you to get max draw with All In
I don't think this is a luxury upgrade at all: I think this is definetly worth considering for any Rogue that has access to it and is running the basic version or Unexpected Courage, or is making heavy usage of Rogue skills. It's just a brilliant card that is ludicrously easy to use and slot in any deck, which is what all skills should aspire to be.
