Control

From Yu-Gi-Oh!

Control 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 a few cards can bend this situation.

Change of Heart, Enemy Controller, Creature Swap, Mind Control, Dark Necrofear and Brain Control are all capable of taking control of your opponent's monster.

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 destroyed or tributed.
