I used to enjoy this game, but when a specific shadow card is withheld from the game purposely, I have lost interest.
I lost over 5000 credits to chase a final card to complete the collection. I have won the same shadow collections at least 5 times over. It is not a good game because of it and unless there is a limit to how many times a collection re-appears and/or is collected, I will delete this game from my games.
