Main Phase (メインフェイズ Mein Feizu) is the fifth phase of a turn. During this phase, the turn player may perform any one of the following actions:

With the exception of playing Z/X Extra, the turn player can do any of those actions more than once as long as he or she is able to do it. If the turn player has done any of those actions and/or choose to not do them anymore, he or she proceeds to the End Phase.


Play a Z/X or Event

Main articles: Z/X Card and Event Card

The turn player may choose a Z/X or Event card in his or her hand, and play it by paying its appropriate Cost. Z/X cards are put into the Square immediately after being played, while Event cards are put into Trash after its effect has been resolved.

Play a Z/X Extra

Main article: Z/X Extra

Once per turn, the turn player may play a Z/X Extra card from his or her Dynamis by fulfilling its Advent Condition or Awaken Condition. Similar to regular Z/X cards, Z/X Extra cards are put into the Square after being played.

Startup Ability

Main article: Startup Ability

The turn player may declare that he or she is going to use one of the startup ability of his or her Z/X, pay the Cost of that ability (if any), and resolve the effects. The turn player can play the startup ability as many time as he or she likes as long as he or she is permitted to do that and is able to pay the Cost of the ability.


Main article: Battle

The turn player may declare a battle and attack with one of his or her own Z/X by turning that Z/X from Reboot to Sleep position. The attacking Z/X can attack any one opponent's Z/X or opponent's empty Player Square adjacent to its own Square.
