During the Main Phase: You can discard 1 card; add 1 "Gravekeeper's" or EARTH Fairy monster from your Deck to your hand. During your opponent's Draw Phase, before their normal draw, if this card is already face-up on the field: Declare 1 card name; look at the card(s) drawn for their normal draw, and if it was the declared card, send it to the GY.
