Numbers are a mathematical object used to reflect the Mana Cost and/or Power of a card.


There are cards that allow you to choose a number as part of their effect. This can range from picking any integer, or being limited to a condition (such as a number up to the number of cards in your hand or other zone.)

Cards in the Episode 3 block were able to refer to the concept of Infinity.

They are also used for the Mana Number to indicate how much mana a card provides while its in the mana zone (either 1 or 0), as well as the Card Number to show collection information.

  • 108. Number
    • 108.1. The only numbers the Duel Masters game uses are integers.
      • 108.1a You can't choose a negative number when choosing a numerical values for an effect.
      • 108.1b Creatures may have negative power. However If you refer to the power of that creature, treat it as 0. For example, If you choose a creature in the battle zone with Hell's Scrapper that was previously made -6000, it isn't possible to treat it as a 11000 card.
      • 108.1c In Duel Masters, ∞ (Infinity) is an unchooseable large number. Creatures with Infinity power that are given an increase are still considered to have Infinity power although an effect that reduces by ∞ is conisdered to have 0.
    • 108.2. If a number is increased or decreased in a Duel Masters game, apply the change in value before other multiplication (such as Doubling).
