Battle position change

A Monster Card’s battle position can be changed in one of two ways: A "manual" change can only be performed during your Main Phase 1 or 2. There are 3 exceptions that will prevent you from "manually" changing a monster’s battle position:
 * 1. A "manual" change. This is when you use your once-per-turn battle position change on a monster, during your Main Phase 1 or 2, to change it from Attack Position to Defense Position or vice versa. This includes a Flip Summon. There are some restrictions on when you can do this (see below).
 * 2. A change because of a card effect. Examples: "Enemy Controller", "Zero Gravity", "Guardian Sphinx", "Book of Moon" and "Tsukuyomi".


 * Exception #1: You cannot "manually" change the battle position of a monster if it declared an attack that turn (even if the attack was negated or a replay occurred).


 * Exception #2: You cannot "manually" change the battle position of a monster if it was Summoned or Set that turn by the turn player.

Please note that:
 * Exception #3: You cannot "manually" change the battle position of a monster if its battle position was already changed "manually" that turn (including if it was Flip Summoned).
 * You CAN always change the battle position of a monster with a card effect, even if any of the above exceptions prevent you from changing its battle position "manually".
 * You CAN change the battle position of a monster "manually" if its battle position was changed by a card effect previously that turn (as long as none of the 3 exceptions exist).
 * Example: You activate "Book of Moon" and flip a monster into face-down Defense Position. Then you can Flip Summon it that same turn, as long as none of the 3 exceptions exist.


 * You CAN change the battle position of a monster "manually" if it was Summoned or Set, but not by the turn player.
 * Example: "Cyber Jar" Summons a monster on the opponent’s side of the field, and the turn player uses "Change of Heart" to take control of it, then Flip Summons it that same turn. This is a legal play (as long as none of the 3 exceptions exist).


 * You CAN change the battle position of a monster "manually" if it was returned to the field because of "Dimensionhole", because it does not Summon the monster (as long as none of the 3 exceptions exists).
