I like how this card works in anime. In the anime, well, it's continuous spell, unfortunately, so can easily get rid by s/t removal.
This is the effect "Banish 1 card in your Deck face-down. If your opponent activates or Summons a card of the same name during this Duel, you can reveal the banished card to negate the activation or Summon of that card, and destroy it".
I like how its effect is omni-negate. Also the banished card cannot be used it for the rest of duel as I can remember and affects both players.
