Shards or Wild Cards are used to create cards, which can be obtained by earning experience points for each Region or Expedition. Once you have looted a few chests, you will obtain some duplicate cards that you already have in sufficient quantity - so you can swap these redundant cards for Shards to create other cards required to improve your deck.
