The '''Ancient Treasures ''' are a [[series]] of cards used by [[Tenzen Yanagi]], as well as [[Yusei Fudo]] briefly, in the ''[[Yu-Gi-Oh! 5D's]]'' anime. The series consists of [[Rock]] monsters with 0 [[ATK]] that inflicts [[effect damage]] to its owner, while some of the associated [[Spell]]s (except for "[[Curse Reflection Doll]]" and "[[Triangle O]]") feature negative effects (e.g. [[pay]]ing [[Life Point]]s, [[discard]]ing, etc.).

These cards are based on ancient objects from various locales around the world. Its theme would later be reused in the form of the "[[Chronomaly]]" [[archetype]] by [[Trey]] in ''[[Yu-Gi-Oh! ZEXAL]]'' (which is acknowledged in {{episode|ZEXAL|34|ref}}, where these cards appear in the background while dialogue explains the inspiration behind the "Chronomalies").

==Playing style==
The main focus of the series is to [[swarm]] the field with Rock monsters and inflict massive effect damage to the opponent. This can be quickly done utilizing the effects of "Crystal Skull", "Ashoka Pillar", and "Cabrera Stone" to quickly [[Summon]] them in order to use "Triangle O" and inflict massive effect damage to the opponent. The Ancient Treasure monsters can also change themselves into [[Defense Position]], preventing the player from taking battle damage.

The main support for this series revolves around [[support]] for Rock monsters and monsters with 0 ATK. "Stonehenge" can be used to [[Special Summon]] a monster with 0 ATK from the [[Graveyard]] in [[Attack Position]], which works in conjunction with the defensive effects of the Ancient Treasure monsters. "Totem Pole" can further enhance these defensive effects by preventing 0 ATK Rock monsters from being affected by an opponent's card effects, in addition to preventing one attack for up to three times. "[[Piri Reis Map]]" can [[search]] for monsters with 0 ATK from the [[Deck]].

The final effect of "Totem Pole" can also double any effect damage, which can be utilized with cards such as "Triangle O". This requirement can be met quicker by sending the player's cards from the Deck to the Graveyard using cards such as "[[Catapult Zone]]", "[[Foolish Burial]]", "[[Foolish Burial Goods]]", "[[Miracle Rupture]]", or "[[Rock Bombardment]]".

However, this series features a number of negative drawbacks, the most prominent drawback including the Ancient Treasure monsters inflicting effect damage to their own controller. "Crystal Skull" can inflict damage to the player upon being [[Summon]]ed, while "Ashoka Pillar" and "Cabrera Stone" inflicts damage to the player when they are destroyed. The only cards capable of redirecting the monster' self-damaging effects are "Curse Reflection Doll" and "Triangle O". In addition, the player must have "Crystal Skull", "Ashoka Pillar", and "Cabrera Stone" on their field to use "Triangle O". If any of those monsters are destroyed, the player would have to figure out a way Summon one of the required monsters to activate "Triangle O".
