Lockpick Chest - Rather than contain cards, it contains 3 Lockpicks. It takes 12 hours to open.

Once you get the Lockpicks, the next time you start unlocking a chest, you automatically use a Lockpick, which cuts the unlocking time by 4x.

So you can unlock your Super Magicals and Legendaries in 6 hours!

Could be about as rare as a Magical/Giant chest. If you don't really know how to use it properly, you could end up simply lockpicking 3 Silvers.
