This is quite an underrated card. It gives you (your ally) +1 health and + 1 sanity for $1 without the need of spending the cost of an action. In most cases, a free action is more valuable than $1. So this card fares better than Leather Coat and Cherished Keepsake, both of which are very fine cards in themselves. Trusted also cost one less than other comparisons like Leather Jacket, and it certainly fares better than Fine Clothes, a more situational card that cost an action to play. In most cases, I also like Trusted over other lv. 0 healing cards ex. (Soothing Melody) because spending actions to do passive healing is, a many have pointed out, one of the least efficient things to do in the game. Another selling point of this card which the above mentioned cards don't have is that it not only gives you more health/sanity protection but gives your ally more mileage. Putting 2 Trusted on allies such as Aquinnah all the sudden turn her into 3h/6s worrior and Beat Cop into a 5h/4s Sergeant. Trusted really maximize their power, getting more values out of their already very strong xp ability.
