Z/X Extra (ゼクス エクストラ Zekusu Ekusutora) is one of the card types in Z/X -Zillions of enemy X- TCG.
Z/X Extra cards were introduced in Booster 16: Code:Dingir - Encounter with Dynamis, and are treated as regular Z/X during the game. Unlike regular Z/X, they are put into the Dynamis instead of regular deck.
A player is able to play a Z/X Extra from their Dynamis once per turn during their Main Phase by fulfilling the Advent Condition (降臨条件 Kōrin Jōken), Awaken Condition (覚醒条件 Kakusei Jōken), or Idealize Condition (夢装条件 Musō Jōken) of that Z/X Extra, with the once per turn limit also shared with Event Extra. Playing a Z/X Extra on the Square follow the same rule as regular Z/X.
If a Z/X Extra left the Square due to any circumstance (e.g. destroyed or moved into another zone), that Z/X Extra is put into the Dynamis in face-up position instead per Rule Effect. In addition, a face-up Z/X Extra in Dynamis cannot be played at all.
In order to play Z/X Extra with Advent Condition in their card text, a player need to fulfill these conditions:
- The number of cards in their Resource is equal to or greater than the Cost of that Z/X Extra.
- They are able to fulfill the Advent Condition of that Z/X Extra.
The Advent Condition is fulfilled by destroying your own Reboot State Z/X on Square that corresponds to the condition written in the text, with the total Cost of the destroyed Z/X being equal or higher than the Cost of the Z/X Extra. After the Advent Condition is fulfilled, the Z/X Extra is played on the Square. Unlike regular Z/X, a player does not need to pay the Cost for Z/X Extra with Advent Condition.
For example, if a player want to play "", they need to have 7 or more cards in their Resource, and fulfill the Advent Condition by destroying 2 of their own Reboot State Red Z/X on Square whose total Cost equal to 7 or greater. The Z/X that need to be destroyed for the Advent Condition can either be:
- 1 Reboot State Cost 3 Red Z/X and 1 Reboot State Cost 4 Red Z/X, or
- 1 Reboot State Cost 2 Red Z/X and 1 Reboot State Cost 5 Red Z/X, or
- 2 Reboot State Cost 4 Red Z/X and so on.
In order to play Z/X Extra with Awaken Condition in their card text, a player need to perform the following steps:
- Pay the Cost of that Z/X Extra like a regular Z/X.
- Fulfill the Awaken Condition of that Z/X Extra by performing the text written on its Awaken Condition.
After the Cost is paid and the Awaken Condition is fulfilled, the Z/X Extra is played on the Square. If the player is not able to fulfill the Awaken Condition, that Z/X Extra cannot be played at all.
For example, if a player want to play "Enlightened Birdman, Were-Crow", they need to pay its Cost (Sleep 5 cards in Resource, including at least 1 Green card) and perform the text written on its Awaken Condition (Return 2 Cost 5 or greater cards in your Resource to deck, shuffle the deck, and put 2 cards from the top of your deck into Resource in Sleep State.)
In order to play Z/X Extra with Idealize Condition in their card text, a player only need to expend the exact amount of required Counter as stated in the Idealize Condition. No other conditions or actions are required when playing Z/X Extra with Idealize Condition.
