• This card is mostly used if you need to activate the specific effects of a Dark World monster (particularly one that destroys something, like Gren, Tactician of Dark World). It is not necessary if you simply wish to revive one of the monsters on the field--use Gateway to Dark World for that.
  • Dark world decks quickly deplete their hands. This is a great card to let you recover, as it's a +1.
  • use this card to save Grapha from its "Death"
