Control

Control (コントロール Kontorōru) is the term used to describe who can use what card on the field. Most of the time, cards remain under the control of their owners, but several cards can alter this situation. Simply put, cards on your side of the field are under your control.

Cards such as "Change of Heart", "Brain Control", "Creature Swap" and "Enemy Controller" allow one to take control of monsters owned by one's opponent.

When a monster switches control to you, place it on your side of the field. It is returned to the original owner's Graveyard when sent to the Graveyard in any way.
