Battle position change

A monster's battle position can be changed in one of two ways: manually or by card effect.

A manual battle position change can only be performed when the game state is open during your Main Phase. It is done by changing the battle position of 1 monster you control.

Each monster's battle position can only be changed manually once per turn.

You cannot change the battle position of a monster manually during the same turn it was Summoned, Normal Set, or declared an attack (even if the attack was negated or canceled due to a replay).

You cannot change monsters to face-down Attack Position whether manually or by a card effect.^[note] Face-down Defense Position monsters are always flipped when changed to Attack Position. This change is called a Flip Summon when it's done manually.
