Z/X Overboost

Z/X Overboost (ゼクス オーバーブースト Zekusu Ōbābūsuto) is one of the card types in Z/X -Zillions of enemy X- TCG. They are debuted in Booster 24: Code:Engage - Evolution Connect.

Unlike other card types, Z/X Overboost cards are comprised of two cards that were combined as one when they appeared in Square: the upper part (上部 Jōbu) and the lower part (下部 Kabu). The upper part is put into the Dynamis and up to four of them can be put into the Dynamis in addition to the 10 Z/X Extra cards in there. The lower part is prepared separately from the deck and only one can be prepared per deck.

During the game preparation, if a player choose to bring Z/X Overboost cards in his or her deck, the lower part of a Z/X Overboost is stacked on the backside of the card so that the front side of the Z/X Overboost becomes the backside of the Player card. Afterwards, the Player card is put face down into the Player Square as usual.

Similar to Z/X Extra, Z/X Overboost are also treated as regular during the game. If a Z/X Overboost would leave the Square due to any circumstance, instead the upper part of the Z/X Overboost is put face-up into Dynamis and the lower part of the Z/X Overboost is turned face-down and put back into the Player Square as Player card in Reboot position.

Make a Z/X Overboost Appear in Square
Z/X Overboost can appear in Square by performing the following steps:
 * Play the dedicated card to perform Ignition Overboost.
 * Perform the Ignition Overboost process as the Event resolves. The detailed process is as follows.
 * Reveal the lower part of the Z/X Overboost.
 * Reveal a face-down upper part of Z/X Overboost with the same name as the lower part from your Dynamis.
 * Join the upper part and the lower part together as a single card, and make the Z/X Overboost appear in empty Square except the opponent's Player Square as Reboot.

All ability possessed or given to the original Player card will not be carried over to the resulting Z/X Overboost, and vice-versa.

Each player may only control one Z/X Overboost in Square, and cannot perform another Ignition Overboost while they still control a Z/X Overboost in Square. The Ignition Overboost process itself is a part of the game mechanic, and does not count toward the once-per-turn limit of playing Z/X Extra from the Dynamis.

The dedicated Event may specify the name of Z/X for the Player to Ignition Overboost into. For example, you cannot Ignition Overboost into a Z/X Overboost without "Azumi" in its card name using "Azumi and Rigel, Oath to the Blue Sky".

While Z/X Overboost is in Square
The following condition applies to player that control a Z/X Overboost in Square:
 * All ability that refer to a specific Player card can refer to the "Player" parameter written in the Z/X Overboost.
 * For example, the ability of your "Sword Sniper, Rigel" is still available while you control "Blue Sky Engage, Azumi Kagamihara" in Square.
 * If the Z/X Overboost does not possess a written "Player" parameter, the "Player" parameter of that Z/X Overboost will take the card name of the original Player card.
 * That player may still make a Z/X appear in his or her empty Player Square.
 * That player does not receive any damage. Moreover, the empty Player Square of that player cannot be attacked by the opponent's Z/X.
