They focus on generating advantage while their Field Spell, "Golden Castle of Stromberg", is on the field, offsetting the Field Spell's large maintenance cost. While not an archetype, the monsters in this series are pseudo-supported by "Golden Castle of Stromberg" being able to Special Summon from the Deck any monster that specifically lists it in its card text, which all members of the series do.
The series focuses heavily on "Golden Castle of Stromberg" to activate its effects. While it has the powerful effects of destroying any attacking monster and Special Summoning any monster member of the series from the Deck, its maintenance card banishes 10 cards from the Deck face-down and is not optional, which can be crippling. Other cards in the series focus on gaining quick advantage when the Field Spell is on the field, to minimise the effects of the cost.
