Card Rules: Rulings powered by The Netrep API. If you activate 'Change of Heart' to take control of 'Revival Jam' , and it is sent to the Graveyard 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 Graveyard as a result of battle. If 'Revival Jam' is removed from the Graveyard 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 Graveyard 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 Graveyard by the effect of 'Call of the Haunted'. [Re: Jam Defender] If you have 'Jam Defender' 'Revival Jam' and a monster equipped with your 'Ring of Magnetism' on your side of the field you may redirect an attack to 'Revival Jam' when you opponent attacks the monster equipped with 'Ring of Magnetism'. [Re: Necrovalley] 'Necrovalley' will NOT negate effects that do not target a card or cards in the Graveyard. So 'Necrovalley' will NOT negate the effects of 'Dark Necrofear' (when destroyed and sent to the Graveyard) 'Winged Sage Falcos' 'Twin-Headed Behemoth' 'Mystical Knight of Jackal' and 'Red-Moon Baby'.
