I chose Skellige in the poll, becuase it was the deck I had most fun with during the KTS event, but I will certainly try to play every faction and give each of them similar amount of time and love, at least during the beta. I suppose that participation in the beta testing is not only a pleasure, but also some sort of duty to try to check every little detail of the game before release, so I would focus on putting into practice as many strategies and card combinations as I can, including the most bizarre, complicated or simply stupid ideas my mind would come up with for every deck. Besides, I believe in the devs that they will make every faction in the game enjoyable and worth playing.
