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:
- Play a Z/X or Event.
- Play a Z/X Extra or Event Extra from Dynamis.
- Play a Shift from Dynamis.
- Activate a startup ability (written as [Boot] in card text).
- Attack the opposing Z/X and/or Player (Battle).
With the exception of playing Z/X Extra or Event Extra and Shift, the turn player can do any of those actions more than once as long as they are able to do it. If the turn player has done any of those actions and/or choose to not do them anymore, they proceed to the End Phase.
Play a Z/X or Event
The turn player may choose a Z/X or Event card in their 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 or Event Extra
Once per turn, the turn player may play a Z/X Extra or Event Extra card from their Dynamis. Z/X Extra are played by fulfilling its Advent Condition, Awaken Condition, or Idealize Condition, while Event Extra are played by paying its appropriate Cost.
Similar to regular Z/X cards, Z/X Extra cards are put on the Square after being played, while Event Extra cards are put face-up into Dynamis after its effect has been resolved.
Play a Shift
- Main article: Shift
Once per turn, the turn player may play a Shift card from their Dynamis if they fulfilled all of the conditions to play the Shift. The turn player cannot play a Shift if they already control one or more Shift on Square.
- Main article: Startup Ability
The turn player may declare that they are going to use one of the startup ability of their 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 they likes as long as they are permitted to do that and are able to pay the Cost of the ability.
- Main article: Battle
The turn player may declare a battle and attack with one of their own Z/X by turning that Z/X from Reboot State to Sleep State. The attacking Z/X can attack any one opponent's Z/X or opponent's empty Player Square adjacent to its own Square.
