Hello, I played hearthstone intermittently from the Beta to Journey to Un'goro, focusing mostly on Arena. I just downloaded the game again, and I have about 7k gold, 9k gems, and a few handfuls of legendaries.

I'd like to try a few wild decks without having to spend any money and it would be nice to know:

1. What are the most common legendaries used? I can realistically craft only 4/5, and I would like to get a good milage out of them. For example, I see a lot of lists run Loatheb.

2. What are the best resources to find competitive and cheap decks? I used to use heartpwn, but I'd like to know if there is a place where we can see the pro's decklists.

2a. Is the wild format played competiteviley, or is the overwhelming focus on standard?

1. Should I disenchant my extra copies or does it make sense to hold onto them for some reason? I remember that a few years ago the consensus was to wait for nerfs to get extra value, but if all my duplicates are old cards, I should probably just get the dust from them, right?

2. How is the general state of things? Enjoyable? Repetitive? Dull? Too expensive? Random? All of the above?

Thanks a lot in advance for the help.
