Heavenly Knight

Heavenly Knights are a LIGHT Fairy-Type sub-archetype of the Sacred Knights. Each Heavenly Knight can only be Xyz Summoned with either Sacred Knights or LIGHT monsters. Lower ranked (4 and under) must detach an Xyz Material at the end of the turn in order to stay on the field, otherwise, it must return to the Deck and Special Summon (usually) lower Level Sacred Knight monster in its place.

As Heavenly Knights contain "Knight" in their name, they can also be considered a part of the "Knight" Archetype.
