I saw other players changing their cards , but I couldn't because there is no change ICON in my game , I wonder why ? And is there anything I can do ? Thanks

It should be on your Roadmap Omar, the 3rd icon down from the top right hand side. There you will have the chance to buy new card skins for 10 gold bars. FYI this is only on the mobile app.
