You will be able to get all the cards from the special machines that you couldn't get before in the VIP machine. This way, you will be able to complete all the card series from your album.
Every time a special machine becomes unavailable and you weren't able to get its cards, these will be added to the VIP machine.
Bear in mind that the gem cost of each card will increase as the number of cards in the machine decreases. That is, the fewer cards in the machine, the higher the gem cost to get them.
