Ancient Treasure

The Ancient Treasures  are a special set of cards used by Tenzen Yanagi in Yu-Gi-Oh! 5D's. According to the anime, it is possible that they are illegal, but currently that is not a problem. This set focuses on monsters with 0 ATK and 0 DEF to do its bidding, and nearly all of those cards have a negative effect (paying Life Points, Discarding, etc.). These cards work well with "Curse Reflection Doll" and "Triangle O" to deflect the negative effects, however. Should they ever be released, typical cards to work with them would be Barrel Behind the Door, Spell of Pain or Megamorph. A List of the Ancient Treasure Cards (as seen in the anime): Crystal Skull, Ashoka Pillar, Cabrera Stone, Curse Reflection Doll, Triangle O, Piri Reis Map, and Totem Pole
