This archetype is divided into a few sub-groups. The main third of monsters, simply called "Adamatia", are explorers of the caves. These include two Level 2 monsters and one Level 4 EARTH monster that allow the player to excavate the top 5 cards of the Deck and Special Summon a Level 4 or lower Rock from the cards excavated. The second is the Adamatia Crysta, Level 4 Rock monsters of FIRE, WATER, and WIND Attributes with 0 ATK and 2200 DEF that have effects when summoned by Adamatia cards and effects to recycle Synchros of their attribute to put on the top of the Deck; these monsters are beasts encased in crystal. The final third are the "Adamatia Rise" monsters, Synchro versions of the Adamatia Crystas, that have excavate effects with bonus effects and Quick Effects if a monster of their Attribute is in the GY on the opponent's turn; these monsters depict an explorer riding on the beast that was freed from its crystalline prison.
