Main Phase 1

In Main Phase 1, the Turn Player may:

• Normal Summon, Tribute Summon, or Set a monster.
• Special Summon a monster(s).
• Manually change the Battle Position or perform a Flip Summon on a Monster Card, provided it was not Set or Summoned this turn.
• Activate effects, such as those of "Barrel Dragon" or "Blowback Dragon".
• Activate or Set Spell and/or Trap Cards of any speed. Quick-Play Spell Cards and Trap Cards cannot be activated in the turn they are Set.

If a particular monster wasn't Summoned this turn, the Turn Player can flip it face-down using its effect (such as with "Guardian Sphinx" or "Swarm of Scarabs"), and then perform a manual Flip Summon on it, since the rules state that one manual Battle Position change may be performed per turn.

At the conclusion of Main Phase 1, the Turn Player may choose to enter the Battle Phase and If he/she chooses not to, play automatically proceeds to the End Phase furthermore both players may activate spell speed 2/3 before proceeding the Battle Phase/ end Phase and it will not cause a replay.(he/she may NOT enter Main Phase 2).
