Have done a fair bit of searching, and I feel like I have a pretty strong deck, but I have read a lot of intelligent views on this that disagree.. I basically ran a BUFF deck and it was really good until now..

I have a weird win ratio right now in 3 star gold, and I'm not able to make it into Platinum it seems..

Just to be clear - I'm looking for decks and guides on what the best players are using (and the ones I found while searching werent great)
