Heeeey, I've done it!
First time legend. Been playing almost a year F2P, mostly arena. I tried for legend once before in February, with mech mage, but with less determination. Stalled out around the top of rank 3 that time. Anyway, here's the list that made it...
Don't think it's optimized at all really. I wanted to tinker with it a few times but I was also afraid to.
In the end, it was good enough.
The reason for only 1 juggler and 1 bow was because I don't own 2nd copies. I'm playing the long game, going for the full collection, and the bow I have is actually the only collectible card I've ever crafted.
I feel like I learned a lot, at least about how my deck matched up against other decks, and how plays/mulligans change based on those matchups. Warriors (especially control) and Warlocks (handlock/Malylock) were my bread and butter. I did surprisingly well against other hunters, even without the Kezan. I had some face hunter stuff mixed into the deck, so with good draws and by summoning random huffers, I was able to outrace even some of the face hunters.
Really glad it didn't come down to the last day. I got gatekept once and ended up 3 stars away before storming back. Before that I'd fallen from rank 1 down through half of rank 3. Not sure when I would've attempted the grind again so it's a huge weight off my shoulders to have made it over the line!
