Whats up with the duplicate cards

You know I think if you use the 5 gem machine I think you shouldnt get 5 of the same card and a stupid card at that. Might as well just use the single gem machine because a stupid card is a stupid card whether you pay 5 gems or 1 this needs attention or get rid of the card idea because as of now it just disappoints people and thats not fun
I have so many matching cards (5 of the same cards) its just stupid Im not even going to play the card machines any more. How can you get 5 of the same card but have so many cards that you dont have? I have a ton of empty categories but a couple of categories I have 3 to 5 of the same card. Stupid
Ok I dont know why but I continued to play those stupid card machines and now Im getting 4 of the same card on the 5 gem machine. These machines are just plain stupid. My new mission is to see how many gems I can save up
