Main Phase

There are only two Main Phases to enter.

Main Phase 1
After the Standby Phase, the Turn Player automatically enters Main Phase 1. In Main Phase 1, the Turn Player may:
 * Normal Summon, Advance Summon, or Set a monster.
 * Special Summon a monster(s).
 * Manually change the battle position or perform a Reverse Summon on a Monster Card, provided it was not Set or Summoned this turn.
 * Activate or Set Magic and/or Trap Cards of any speed. Instant Magic Cards and Trap Cards cannot be activated in the turn they are Set.

After Main Phase 1 has ended, the Turn Player may choose to enter the Battle Phase. If he/she chooses not to, the player automatically proceeds to the End Phase (he/she may NOT enter Main Phase 2).

Main Phase 2
At the end of the Battle Phase, the Turn Player can enter Main Phase 2 instead of the End Phase. In Main Phase 2, the Turn Player may do the same things done in Main Phase 1 if have not been perform to do so. If the Turn Player has Normal Summoned or Set during the Main Phase 1, you cannot Normal Summon or Set as these actions can only be done once per turn. If the Turn Player have not manually change the battle position of a monster that has not been Summoned this turn nor attacked, the Turn Player can perform this action.
