Suggestion for Dream Cards

Hi, development team:
Currently some dream cards are sold below the amount of XWG they represent. This is mainly because some users urgently need to sell the cards.
If the project team can buy back the cards from the market if they are sold less than the value they represent, it will increase the liquidity of the dream cards. It will build the confidence among players.
It would be great if the project team can buy back cards from market on a weekly basis. So that other players will still have the chance to find good cards with low cost on the market.
