So far, Favor cards are exclusively found in , with a few neutral cards on the side. They don't initiate skill tests, so you're getting this to discount Intel Report and the like. Not bad if you have a lot of such cards, but for 3 XP you should get more. It's a good thing Relic cards are found across many classes, and there's a splash of Ritual cards for all of the classes, too. So, while most Rogues and Dexter Drake may take advantage of all three traits, the main value of this card for everyone else will be discounting Relics and Rituals. Should you take this card? If you need the money, and you know you want those cards, then yes. Because there's powerful Rituals and Relics across the board, you'll know if this fits in or not.

One more note: Rituals don't really initiate skill tests either, but there are a few Relics that do (and Relics sure are expensive anyways), probably the most interesting are the neutral weapons Ornate Bow and Timeworn Brand. Enchanted Blade is another interesting option, since Mystics would like a boost to repeatedly use this weapon.

I tried to put this in Sefina with ornate bow and some favor cards. It was not a particularly great deck, in general I find Sefina a bit challenging especially on harder difficulties, but it did really allow this card to shine.
