A classic card for Criminal and any other factions planning to use ressources. On face value, it seems to be worth 1 less than Sure Gamble. But that is not the case.
Let me explain : if you want to use the credits to install a ressource, with Sure Gamble you'll need to play it first, costing you 1. And then play the ressource (costing you 1). All this would have cost you 2, gained 4 and spent XX amount of credits on the ressource.
If you use Career Fair, you would play Career Fair (costing you 1) and this would install the ressource, saving 1 compared to the scenario of using Sure Gamble. On the basis that 1 = 1 (a click is worth slightly more in fact), you get the same value as Sure Gamble.
Not only that, but since it cost 0, you can play it even if you have very few (even none) credits in hand, compared to Sure Gamble which need you to have 5 in hand.
The most efficient use is when you want to install ressources that have a cost of 3 and more. But for tempo value, you can use it even on a 2 ressource, depending on the situation, to get to use that ressource immediately (like running an unrez ice with a newly installed Hernando Cortez).
In my opinion, if you can consider slotting this card if you have at least 6 ressources cards in your deck. The more ressource cards you have, the easier it is to use. Because, contrary to Sure Gamble, it has no value if you do not have any ressource in hand to play.
The other comparable card is of course, Modded. But there are more ressources to play that have a cost of 3 and more. The most common ressource cards used with Career Fair are probably : Earthrise Hotel, Daily Casts, The Class Act, DreamNet, Xanadu and Liberated Account.
Evocative art and quote. I would have prefered something that evoke more a criminal aspect. This feel like a corp card. Still, a good card that has been around for a long time.
