Main phase

The main phase is both the second and fourth phases of a turn. Non-instants can usually only be played during this phase, only by the active player, and only when the stack is empty.

The following events occur during the main phase:

• Abilities that trigger at the beginning of the main phase go onto the stack.
• The active player gains priority.

Once per turn, the active player may play a land from his or her hand during this phase while the stack is empty. This is considered a Special Action which does not use the stack.

When both players yield priority in succession while the stack is empty during the pre-combat main phase, the game proceeds to the combat phase. After the combat phase is complete, the game proceeds to the post-combat main phase.

When both players yield priority in succession while the stack is empty during the post-combat main phase, the game proceeds to the end phase.
