Talented Healer doesn't work as trait

As stated on the title, the card is a trait, and I have to play it at the start of my turn.
But it doesn't stay on the character (it has Duration 3), it goes on the discard pile the exact moment I play it.
The card is grayed, maybe it means something.

 

I think cards like that have not yet been implemented - that is I don't think that all of the behaviour has been defined (and in that case, artwork).

 

Unimplemented cards also display their item as black icon, for example Perfect Lifesteal.

 

Ok, thanks.
I found other cards grayed out, and your answers are exactly what I thought.
