Where can I find a list of standard/wild cards?
Click on “My Collection” This will display the cards in your collection. Click on the Book icon in the lower left and you can opt to see all cards, just cards in the current standard set, or just cards from one of the expansions. It will also show which sets are part of standard and which sets are wild only. If you want to see all the cards, not just those that you currently own, click on the “Crafting” button (lower right) Normally this will not show Basic or other uncraftable cards however you can show these cards as well by selecting “Include Uncraftable Cards” in the right panel.
