To change deck cosmetics you can go to the deck editor then on the top right select the "deck box miniature (with sleeves and the coin)", after that you can choose from the available deck boxs sleeves and coins (you can buy those that are unavailable).

For avatar cosmetics you can go to your profile screen and from there change your shirt and other avatar cosmetics.
