Some restrictions apply when designing your deck. For instance, you can only bring 12 cards into battle. You do so by placing unlocked cards from your collection into your deck. You can arrange your deck in the Deckbuilder. You can have multiple decks using the "Add deck" button at the top of the screen in your lair.

Earn new cards by playing through the story mode, opening packs of cards, and crushing your opponents in real-time Player vs. Player combat!
