●You gain control of the targeted monster in the same Battle Position that it was in on your opponent’s side of the field. If it is face-down you may Flip Summon it and any Flip Effect is activated. During your End Phase it is returned to your opponent’s side of the field in the same Battle Position as you last had it in. So if you attacked with the monster and it remained in Attack Position, it will return to your opponent in Attack Position.
●You can use the monster you control through the effect of Change of Heart as a Tribute for a Tribute Summon, or for an effect like Cannon Soldier’s.
