Ragnarok, the Divine Sword of Savior (MP01-104 R) [Masterpiece "Pilgrim-Memories"]

As you play this card, target a J/resonator. If that J/resonator is still a legal target, put this card into the field added to the chosen target, otherwise put it into its owner's graveyard. Added J/resonator gains [+500/+500]. If a resonator dealt damage by added J/resonator this turn would be put into a graveyard, remove that resonator from the game and you gain life equal to its DEF.
