Which game mechnic you'd like to see it return?

[DRK3]

There is too many amazing artwork cards in TB not to be re-used in Gwent. I would estimate at least 30-40 cards. And the first should be Meve!

Haunt would probably be cool, and could come with an entire bunch of cards (noonwraith, nightwraith, wraith, barghest, plague maiden at least, and maybe even just a plain old ghost).

Moonlight was really fun to play with, so I wouldn't mind see it return. The only "weather" I really played; its versatility was useful.
