Cost (コスト Kosuto) is what is needed in order to play a card. It is also known as Resource Cost (リソースコスト Risōsu Kosuto).

Overview[]

The Cost of a card is located in the upper left corner of the card, just below the card type. To pay the Cost of a card, Sleep a number of cards in your Resource, equal to the Cost of that card. Also, you must Sleep at least one card with the same color as that card. For example, in order to play "Queen of Desert, Cleopatra", a Cost 3 Red Z/X, you must Sleep at least one Red card and two other cards of any color in your Resource. Colorless Cost can be paid with cards of any color, while cards with 0 Cost can be played without requiring you to Sleep any Resource.

Several cards are able to reduce the Cost of a card (e.g., "Country-Eating Manticore"). However, almost all of them also come with "the Cost cannot be 0 or less." clause, preventing the player from playing the card without paying the Cost. Some cards (e.g., "Four Archangels - Michael S.K.") may instead possess an ability that allows the player to play a card without paying the Cost. Conversely, there are cards that are able to increase the Cost of a card as well, most often its own Cost as a kind of restriction.

For the list of cards grouped by its Cost, see Category:Cards by Cost.

Infinite (∞) Cost[]

Infinite Cost (written in the card as "∞") cannot be paid normally, and mostly exists on Token. In addition, cards with infinite Cost cannot be affected by effects that refer to the Cost value.[1]

Cost of Ability[]

Startup Ability also has its own Cost, which is shown as <○○> or 【コスト】 ○○ ( <Cost> ○○ ) in the card text and must be paid in order to use the ability. All Resource Cost in ability is written in form of Color Icon followed by a number (e.g., [1 Red] "1 Red"). Other than Resource Cost, the Cost of ability may also require you to [Sleep] (Sleep) the card or to do some other action. If the ability listed more than one Cost, all of them must be paid.

If the Cost of an ability is only written as [0 Colorless] ("0 Colorless"), the player does not have to pay any Cost to use the ability.

Some abilities will instead require the player to pay a Resource Cost as part of its effects, which itself is not the actual Cost of that ability, but still follow the same procedure for paying a Resource Cost.

Multicolor Cost[]

When paying for the Cost of multicolor cards, at least one card of each of its colors must be Sleep for the Cost. For example, in order to play "Sister-Caring Sweets Craftsman, Rosette of the Gourmet Lounge", a Cost 3 Black and Red multicolor Z/X, you must Sleep at least one Black card and one Red card alongside one other card of any color in your Resource. You cannot choose to pay its Cost with only Red cards or only Black cards.

If the Cost of a multicolor card is less than the number of colors possessed by that card, the color that must be Sleep for the Cost is reduced by one for each of its differences. For example, the aforementioned "Sister-Caring Sweets Craftsman, Rosette of the Gourmet Lounge" that has its Cost reduced to 2 in your hand still requires you to Sleep one Black card and one Red card to play it. However, if its Cost is further reduced to 1, you only need to Sleep either one Black card or one Red card to play it.

Icon for Cost in the card text sometimes will have two Color Icon that precede the number (e.g., [1 Black/Red] ). In that case, it will follow the same procedure as paying the Cost for multicolor cards.

Comprehensive Rules[]

203 Cost

  • 203.1 The cost needed to play a card.
  • 203.2 Cost is displayed as a numerical value, and determines the amount of Resource to Sleep when playing a card (805).
  • 203.3 If Cost value is displayed as ∞, the Cost of that card cannot be referred to, it cannot be chosen by compensation or effect that requires Cost value, and it is unaffected by effect that requires Cost value.

805 Resource Cost and Payment

  • 805.1 Playing a card or ability, or dealing with something inside the text, might require you to Sleep Reboot State cards in Resource as compensation. This compensation is called Resource Cost.
  • 805.2 Resource Cost always has a point as its information, and may also have color as well.
  • 805.2a Resource Cost to play a card has all of the colors (204) possessed by the cards as its color, and the Cost (203) value of that card as its point.
  • 805.2b Resource Cost indicated by an ability is written as "[color] [point]". In this regard, if the color part does not exist, the Color Icon will use the None Colorless Icon Colorless instead.
Example : "[2 Red]" means Resource Cost with Red color, and point of 2.
Example : "[1 Colorless]" means Resource Cost with no color, and point of 1.
  • 805.2c If the Cost for playing a card or ability is increased or decreased by a specified number, it increases or decreases the Resource Cost for playing that card or ability itself. If there are increases and decreases by multiple effects that apply simultaneously, the increases are applied first, then the decreases are applied after that. If the Resource Cost for playing that card or ability does not exist, it is treated as having a Resource Cost without all colors and a point of 0 for calculating the increases and decreases. In addition, the point of a Resource Cost cannot fall below 0 by Cost decrease.
  • 805.3 If a player pays Resource Cost as compensation, that player performs the following process.
  • 805.3a For each color in the Resource Cost, choose 1 Reboot State card with that color in that player's Resource. However, if the amount of type in the Resource Cost color exceeds the Resource Cost point, the cards that need to be chosen this way are reduced by 1 for each of the excess. In doing so, that player can arbitrarily opt to not choose the card that corresponds to a particular color.
Example : If that player plays a card with Resource Cost "[Red] [0]", that player does not choose any Reboot State card in Resource for this section.
Example : If that player plays a card with Resource Cost "[Red-Blue] [1]", that player needs to choose either 1 Reboot State Red card or 1 Reboot State Blue card in Resource for this section. Which one is chosen is up to the player.
  • 805.3b Choose a number of Reboot State cards in that player's Resource, equal to the Resource Cost point subtracted by the number of cards chosen in 805.3a. At this point, the cards chosen in 805.3a cannot be chosen again. If the number after being subtracted is 0 or less, no cards are chosen here.
  • 805.3c If the specified number of cards in 805.3a and 805.3b cannot be chosen, that compensation cannot be paid, and the process that requires the payment of that Resource Cost cannot be performed.
  • 805.3d Sleep all cards chosen in 805.3a and 805.3b, and the payment of the Resource Cost is completed.
