Deck

The cards a player has access to during a game are determined by their deck. A deck is a selection of 10 cards from the player's collection. Every deck is associated with a Planeswalker.

Custom and pre-built decks

Pre-built decks are provided by the game. There is the "Custom 1" deck that each Planeswalker starts with; new cards from it are added to the player's collection, and duplicates give Orbs as usual. These decks can be customized, and can be far more powerful than the pre-built decks. They may be saved in a Planeswalker's deck slots, to be easily reused in later games. They may be renamed to the player's purpose, and added to a list of Favorite decks. Slots in the Planeswalker list and Favorites list are limited. One additional slot for a Planeswalker may be purchased by spending Runes, and another with Crystals. One may be purchased after subscribing to a VIP Pro plan, and two others on the Master plan. Favorites slots may be similarly acquired, but are also one-time rewards for rising to certain XP levels.

Each Planeswalker each has a pre-built deck list, a collection target composed of cards which the player is less likely to own. Completing these decks gives rewards; eg Beginner deck completion grants Runes, the Master deck, five Mana Jewels, and the Expert deck, twenty Mana Jewels.

The Training section of the Story encounters, and certain Events, will occasionally require the player to use their special pre-built decks.

Deck restrictions

Decks may only contain cards meeting Color requirements and card type requirements. These requirements depend on the Planeswalker for which the deck is being built. Some events further restrict decks based on card set.

• The color requirements of a deck are determined by the color affinity of the Planeswalker.
  • For example, the deck of a Planeswalker with affinity for blue and green may only contain cards which are blue, green, or colorless.
• The deck limits of the Planeswalker set the maximum number of cards of each type (Creature, Spell, or Support) which may be included in a deck. Deck limits increase at higher Planeswalker levels.
• The card sets which a deck may contain cards from are determined by the event format.
  • Standard format event decks may only contain cards from a number of the most recent card sets, plus Origins and Puzzle Masters.
  • Legacy format event decks may contain cards from any set.

During the game

The 10 cards in the chosen deck are the basis of the player's library. During a game, cards are drawn from the top of a player's library.

The library is initially formed by shuffling together 4 copies of each card in the deck. Whenever more cards are needed in the library, a further 4 copies of each card in the deck are shuffled together and added to the bottom of the library.
