アダマスの守り手 (Guardians of the Adamasu)

Somewhere in this world one can find the remains of a king of great power slumbering untouched. Only the Guardians of the Adamasu — soldiers of departed spirits gifted with the meaning of “indomitability” — can find the road leading to where the king’s remains are hidden. 
 You are an observer who has been entrusted with the mission of finding the king’s remains before any other observers.

In the first stage of play, players puzzle together Mana cards to form rhombuses of different colors. After a one minute period where players can adjust the orientation of the Mana cards in their hand (but NOT the order), players then race to place cards from their hand to create the right rhombus(es) for the unit card they wish to acquire.

Using the acquired unit cards (with assigned power points based on Mana main and sub colors), the first player to inflict 8 damage points upon the other wins the game.
