"Queen", "King", and "Jack's Knight" were known as The Three Swordsmen possessing the maximum speed Summon ability.[citation needed]
Playing style
The main purpose of this series is to swarm the field using the effect of "King's Knight", which can only be activated if "Queen's Knight" is on the field, and is used to Special Summon "Jack's Knight". They can be used either as Tribute fodder, or to fuse them to Summon the ultimate monster, "Arcana Knight Joker". " Since "King" and "Queen's Kight" are Level 4 monsters, they can easily be used as Xyz Materials.
