If you have to ask, maybe not. But if you are a proficient rogue player then yes, miracle secret rogue, while not a tier 1 deck, is certainly a serviceable deck in the right hands. And fun to play to boot
It's a solid deck. I've been playing the one thijs has been using in GMs with a 60% win and I'm not a good rogue player by any means. Worst matchup is bomb warrior and demon hunters. Is good against most others.
Secret Rogue is still a "good deck", but it has lost ground after the nerf to Secret passage etc and is no longer a high tier deck. Still has some good matches but is a lot more reliant on High-RNG rolls.
