Witchcrafters are an archetype of Spellcaster-Type monsters that turbo out a lot of powerful spells and said spells can add themselves back during your end phase, if you did not activate their primary effect that turn. They have recently gotten new support in the form of a fusion monster and an archetypal fusion spell.
