After losing all of his limbs, Uther has returned with top of the line cedar appendages. If this Black Knight and his minions usurp the rulers of the kingdom and place it under Uther's control, then they will be awarded futuristic items from the Dark Alchemist. Uther's reward will include a traveling device called a "Car" with the power of 200 horses.
Each mastery level adds another card to the cardpool for defeating Uther. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
