"Laundsallyn", known as "Lancelot" (ランスロット Ransurotto) in the OCG and English anime and manga, is a small archetype consisting of monsters that represent Sir Lancelot. It was first introduced in the TCG version of Abyss Rising, but received its first support in the TCG version of Primal Origin with the release of "Avalon".
Due to its Japanese name, "Number 23: Lancelot, Dark Knight of the Underworld" also falls into this archetype. However, because TCG and OCG support for this archetype only works on "Laundsallyn" monsters that are also "Noble Knight" monsters, this is not an issue.
