Each card in the game has a Senior Version. Veteran cards are better versions of regular cards that players can unlock when they reach level 15 of the regular card.
Players have the option to enter battle with a regular or veteran version of a card. They cannot enter battle with two cards that are the same (normal and veteran at the same time).
Veteran cards have a distinctive gold frame and bonus stats that are displayed slightly differently than regular cards.
When a balance change is made on a Normal card, a change is also made in the stats of its Senior counterpart.
