RegisKillbin made a video on this deck recently, so youll probably see some of it this week. The deck is designed to gain ludicrous amounts of armor.
I don't see why it wouldnt be favorable against a lot of wild decks that are popular as its heavy in control tools. Idk how it deals with cubelock without shuffling several brawls in the deck with dead mans hand. It does have coldlights so you can mill decks like that. Youll almost never see the armor remover card either.
No tools for res priest though so you might as well not play it. You will see one of them daily and even the standard version on wild ladder. Best thing to do is rope them every turn and spam emotes
You need to be able to beat Warlock, Paladin, Mage and DH to be viable in Wild (well, some combinations, as the deck to beat them all doesn't exist). This beats only 2 of them (Mage arguably, because while it beats Secret, it loses to Quest and Reno), loses badly to the other two. It's a nice deck, but has very unfavorable spread of match-ups. You could get away with losing badly to literally anything else apart from those 4 classes, but if you get crushed by like half of the meta, you are not gonna have good results.
If Warlock and Pala were a bit less popular... But they aren't, Lock is the second most played class. Mage as a whole is first, but only roughly 7% accounts for Secret.
