Support Card Restrictions
There are a few different reasons why you might not be able to use a support card.

- The message above the second support card is saying that you can’t use it while training that uma. Since the uma being trained is King Halo, I cannot use King Halo’s support cards.
- The message above the third support card is saying that another support card of the same uma is present. The deck already contains the Speed version of Special Week, so I can’t add the Guts version of Special Week.
- The message above the first support card is simply saying that the card is already present in the deck.
