What does your My Collection tab look like?
can you post a Screen Shot?
If your cards are GRAY ( not In Color )
that means they are NOT DOWNLOADED.
you have to Download them to be able to play them.
If your cards are Not Brightly colored, then they are not Active.
a card or Cards must be Active to play them.
Picture One shows that I have Gray cards that Need to Be Downloaded.
Picture Two shows that Al my cards are DIM colored ( Not Active )
But One Card I selected and made it Active with the Green Check mark.
