How to see alt art Pokémon ex and use them in a deck

Dadigipro2424

whenever I try to make a deck I can not see the alternate art cards I get from the battle passes

In the deck editor you have to select the card you want to see, then when the card gets enlarged you select the "Available" dropdown just below the card and in the new popup window move rigth/left to view all the available rarities.
