"Revendread Origin" Rating Score by とき

A Ritual Spell that seems to be incompatible with Pre-Preparation of Rites at first glance, but can be paired with a slayer in a diagonally upward manner.
It has the effect of ritual summoning a wide range of Vendread Ritual Monsters from the hand or her GY, and the effect of excluding it from her GY to destroy the slayer.
Its performance as a Ritual Spell is super-dreadnought. Not only the field and hand, but also GY's undead can be used as a cost, and the descending Ritual Monster can also be put out from the hand or GY. However, due to the restrictions of Vendread juniors, Vendread juniors want to mainly use materials from the field. Therefore, I can't help feeling that the strength of this card is somewhat killed.
If you take advantage of the undead exclusion from GY, one way would be to use his Shiranui card that activates the effect with exclusion. However, since he is now able to remove Vendread as well, removal has become a strength of the card, and the number of Vendread Rituals has increased, so its importance has skyrocketed. The effect that protects the slayer is that he has a way to salvage this card from GY, so I want to use it when it's really dangerous.
