I hope you realize that by revealing the Secret achievements, you can't put them on Outofcards because people will now know what they are.
But anyways, time to get some of these achievements. I now have a reason to make my first deck on this site, and just put all of the Secret achievement cards in it.

Thanks to CoolStoryHub for making the original - https://www.hearthpwn.com/decks/1280801-easy-secret-achievments-deck
Before the deck I had 9 Gold, 38 Silver, 208 Bronze. After the deck, I now have 13 Gold, 50 Silver, and 212 Bronze.
