There are various options to sort your cards here. You can sort by name in the center of the page if you know the name of a specific player:
On the left hand side, you will see a number of other options for sorting. First up is sorting by regular or Gold foil (if you're a Splinterlands player, this will be familiar). Gold foil cards are more rare, and will potentially offer other benefits in the future, in gameplay as well as rewards. As you can see below, Gold foil is selected (you can unselect one or more sorting options by clicking the X to the right side).
There are two gameplay related sorting options as well, 'Role' and 'Position'. Role will allow you to sort player and coach cards, and position to sort by goalkeeper, defender, midfielder, and forward.
Finally, you can sort by 'Status', which is split into three categories: All Cards (this shows every card in the game, including what you own), Owned cards that you have received from packs (or in the future, from markets or other players), and Not Owned cards that you do not yet own but exist within packs/the game.
Finally, after selecting specific categories on the left side, you can go to the top right of the cards section and sort these cards in different orders, such as highest to lowest passing skill, lowest to highest blocking, etc.
