Rulings
- If you activate Change of Heart to take control of Revival Jam, and it is sent to the GY as a result of battle, the owner (not you) gets the option to pay 1000 Life Points to Special Summon Revival Jam to their side of the field.
- The cost of 1000 Life Points is paid when Revival Jam is sent to the GY as a result of battle. If Revival Jam is removed from the GY before your next Standby Phase by cards like Disappear you do not get your Life Points returned to you.
- If you pay 1000 Life Points when your Revival Jam is sent to the GY, and then activate Call of the Haunted to return it to the field before your next Standby Phase, and it is again destroyed you must pay another 1000 Life Points if you want it to return during your next Standby Phase. Its condition was reset when it was taken out of the GY by the effect of Call of the Haunted.
