While Card Wars Kingdom has a lot of cards and creatures that are available to everyone, the game has released some content that was only available for a short time and now is unavailable. This limited time content includes both Creatures and Heroes.
Limited Time Treasure Cave Algebraic Creatures Edit
During the first few months after CWK's release, the treasure cave offered the chance for certain creatures to be won from 500 gem chests at a higher percentage. These creatures include:
Epic Dungeons Edit
Two epic dungeons were released in October of 2016. One was for the creature 238 Plain Jane and the other was for the creature 240 Husker Dragon. A third epic dungeon for Sandor was advertised but was never released. A player had to defeat the dungeon battles to have a chance to obtain Plain Jane or Husker Dragon.
Note: All three Epic Dungeon creatures can be awakened. Shards can be looted from Adventures.
Limited Time Heroes Edit
Three limited time heroes were released during the months of October, November, and December of 2016 (each hero for only one month). These include BMO, Earl of Lemongrab, and Ice King. Anyone could buy them, and they cost 3000 gems each.
You can see them in this Imgur album.
