D. Battle Phase Once attack preparations have been made in Main Phase 1, you enter the Battle Phase. If you do not wish to conduct a Battle Phase, your turn proceeds to the End Phase. Keep in mind that the starting player cannot conduct a Battle Phase in their first turn, even if they have placed a Monster Card on the field.

Quick Reference Chart

		Start step - Declare that you are entering the Battle Phase. You and your opponent may both play Quick-Play Spell and/or Trap Cards. Battle step - Select and announce 1 monster to attack with, and declare 1 of your opponent's monsters your target (the monster you wish to attack). You and your opponent may both play Quick-Play Spell damage. Damage step - Calculate the damage points of the designated monsters. If a monster has a Flip Effect, apply it immediately after damage calculation. However, a Flip Effect does not affect monsters that have already been destroyed as a result of damage calculation. End step - Resolve all battles by repeating the Battle and Damage Steps as many times as necessary, then declare an end to your Battle Phase. You and your opponent may both play Quick-Play Spell and/or Trap Cards.

I. Start Step Announce that you are going into Battle Phase. Quick-Play Spell and/or Trap Cards can be played by either player at this time.

II. Battle Step During their respective turns, players are allowed 1 attack for every monster on the field in face-up Attack Position. However, a single monster can only attack once per turn. The attacking player chooses 1 of their monsters and designates 1 of the opponent's monster as a target. Play then proceeds immediately to the Damage Step, returning to the Battle Step if the attacking player wishes to attack again with another monster. If the opposing player has no monsters on the field, the selected monster's attack will inflict Direct Damage on the opposing player's Life Points (Direct Damage). A monster in the Attack Position does not have to attack. Depending on the situation, you can choose whether or not a monster will participate in battle. Once a monster attacks, it may not be changed to Defense Position in the same turn. In addition to monster attacks, both players may use their Quick-Play Spell and Trap Cards during this step.

Replay Rules

		Returning gameplay to a previous step and playing that step over again is known as a "Replay". For Example, if the number of your opponent's monsters on the field change due to the effect of Trap or Quick-Play Spell Cards during your Battle Step, a Replay is triggered. When this occurs, play returns to the beginning of the Battle Step with the attacker choosing a new attacking monster and target. Replays can only be triggered by the effects of Trap or Quick-Play Spell Cards. Example: During your Battle Step, you have declared an attacking monster and designated an opponent's monster as a target. Your opponent then activates their "Ultimate Offering" Trap Card, allowing them to summon another monster to the field. Since your opponent now has a different number of monsters on the field than they did when the Battle Step began, a Replay is triggered and you may again choose a monster to attack and designate a target for the attack. Because a Replay returns play to the beginning of the current Battle Step only, monsters destroyed in previous Battle Steps are unaffected.
