Deck

• A player’s deck can either be a legal commander deck following the Commander variant rules from the Magic: The Gathering Comprehensive Rules or a raider deck following the rules from the Raiders Comprehensive Rules.
  • For deckbuilding, raiders is an eternal format where all cards are legal except acorn cards and conspiracy-type cards.
• A raider deck consists of at least 40 cards plus a commander.
  • While there is no upper limit, a deck must be able to be sufficiently shuffled in a reasonable time frame.
• When choosing a commander, you must use either a legendary creature, a planeswalker, a non-creature permanent with the ability to be commander, a pair of legendary creatures or planeswalkers that both have partner or a legendary creature that has Choose a Background paired with a background legendary enchantment. The chosen card or pair is called the commander or general of the deck.
• No cards in any player's deck may have a color identity that does not match or is not a subset of the color identity of the commander(s). The color identity of a card is composed of its colors plus the colors of every colored mana symbol that appears on the card, whether in its mana cost or its rules text; for double-faced cards, the colors and text boxes of both faces count. Hybrid mana symbols count as both halves' colors for this purpose.
  • Mana symbols on basic lands count, as do mana symbols granted by basic land types on nonbasic lands.
  • Mana symbols in reminder text do not count.
• In addition to color identity, a raider deck may only have a maximum number of cards of a certain printed rarity and a maximum number of cards with the same name based on the printed rarity all based on the size of the deck. The chart below describes the relationship.
  • For the purposes of deck construction, cards with interchangeable names have the same English name.
  • A card’s lowest printed rarity is used when considering a card’s printed rarity.
    • For example, if a card was printed as both rare and common, it is considered common for deck building purposes.
  • There are three tiers of deck sizes. Those tiers are forty (40) cards, fifty (50) cards, and sixty (60) cards.
    • If the size of a deck does not match one of the tiers exactly, it is considered the largest size tier smaller than their deck size.
      • For example, if a deck has fifty-three (53) cards, it is in the fifty (50) card tier.
    • The size of a deck and card rarity deck building considerations do not include the commander and sideboard.
    • All deck size tiers may have any number of common cards.
    • All deck size tiers may have only one (1) rare, mythic, timeshifted, masterpiece, and special cards of the same name, two (2) uncommon cards of the same name, and four (4) common cards of the same name.
      • Cards with rules text that alters how many cards with a specific name may be in a deck do not abide by these limits, but they still count towards the total number of cards with that rarity.
    • All lands are considered a rarity lower than their lowest printed rarity for deckbuilding purposes, to a minimum of common.
      • For example, if a land’s lowest printed rarity is rare then it can be considered uncommon.
    • Cards of a higher rarity may be traded down to allow for additional cards of a lower rarity.
      • Mythic, timeshifted, masterpiece, or special rarity cards may be traded down to allow for one (1) additional rare card.
      • Rare, mythic, timeshifted, masterpiece, or special rarity cards may be traded down to allow for  two (2) additional uncommon cards.
    • Each deck size tier restricts the number of cards of a particular rarity.
      • For the 40 card deck size tier, in addition to common cards, a deck may have only one (1) mythic, four (4) rare, and eight (8) uncommon cards.
      • For the 50 card deck size tier, in addition to common cards, a deck may have only two (2) mythic, five (5) rare, and ten (10) uncommon cards.
      • For the 60 card deck size tier, in addition to common cards, a deck may have only three (3) mythic, six (6) rare, and twelve (12) uncommon cards.
