It can help fulfill this card's Graveyard requirement.
"Trade-In" sends a monster from the hand to the Graveyard, while this card returns monsters from the Graveyard to the Deck, and both cards net more cards.
This combo can be easily repeated by helping you draw other copies of "Trade-In", this card, and/or Level 8 monsters.
This card works well in a Deck that makes extensive use of an Extra Deck containing monsters of different Types.
When Xyz Monsters are Summoned from the Graveyard, they typically do not have Xyz Materials, which usually prevents them from using their effects. This card can return Xyz Monsters to the Extra Deck, so they can be re-Summoned with Xyz Materials.
This card works well in Decks that use hand traps with different monster Types from the rest of the Deck.
"Zombie World" shuts down this card, as it turns every monster in both player's Graveyards into Zombie-Type.
