I can't get the achievement"?"

Good day to you, dear Blizzard company. I’m having trouble with your secret achievement called “???” in the game Heartstone, which involves solving a puzzle by fighting an innkeeper multiple times in Training mode. As far as I remember, to open the very first puzzle you need to play five spell cards in the “Rogue” class, namely: “Intimidation”, “Machination”, “Now mine!”, “Cheating”, and “Potion of Illusion”. I’m playing your wonderful game on a mobile device (MIUI Global 12.5.3), and when I play it this way, I don’t have the very spell “???” that is needed to open the puzzle itself. This achievement is important to me because the reward for it is quite valuable. Maybe this is due to some bug in the patches? Or should this achievement only be obtained in the computer version of your game? Please answer me by email if the problem is solvable or you can credit me with this achievement for my hard work in trying to get it (I tried to get it for more than a week).
Thank you for the opportunity to leave such messages.
