Characters can get a lot of daily threads from the daily Trove of the Treasure King scenario in MoP Remix!
In order to unlock the Trove of the Treasure King scenario in MoP Remix, you need to unlock the Isle of Thunder. In Mop Remix, you must be at least level 50 and complete the quest chain which starts with Thunder Calls (Alliance) or Thunder Calls (Horde).
Once you unlock the island, keep continuing along the quest chain until you unlock Dailies.
Every day, the first time you turn in the Aid the Kirin Tor Offensive or Aid the Sunreavers Onslaught quest, you will get a Key to the Palace of Lei Shen. This is your entry ticket into the Trove of the Treasure King scenario. You can only earn one key a day, so even if you can't run the scenario, you can stock up on the keys and grind them all out whenever you have time.
You can enter the scenario as many times as you have Key to the Palace of Lei Shen. If you have the quest A Fresh Scene, completing the Trove of the Thunder king counts as a scenario as well.
The goal of the Trove of the Thunder King is to loot as many chests as you can before the 5 minute timer runs out and then make it to the exit. For every chest you open, there is a chance for a Burial Trove Key to drop, which allows you to open bonus chests at the end. If you make it to the exit within 5 minutes, you get an extra Burial Trove Key. If you don't, you don't get the extra key but you get to still open bonus chests as the end.
There are 4 main rooms, separated by 3 locked doors. In order to open the locked doors, you need to pull a lever. Once you pull the lever, the door will open and you're able to continue!
