Use this card against "T.G. Hyper Librarian" decks, since the first Synchro Monster they need to Summon is Level 5. Without that, they can't perform the loop.
This card is useful against "Nekroz" and "Shaddoll" Decks, since this card prevents them from recovering resources through their Ritual Spell Card effects (for "Nekroz") or Fusion Monster effects (for "Shaddoll").
