"Exodia Necross" Rating Score by みめっと

Even in the original rare hunter battle, it is mentioned that Exodia parts are sent to his GY = Exodia Deck loses the winning line, but a monster that can be produced by sending all of his Exodia parts to GY The idea of a surprise production that overturns common sense is a very good card.
However, I have to say that the performance of the monsters that come out using his spell, which satisfies the difficult conditions and does not have a dedicated search method, is not worth it at present.
Originally, its ATK was that of a low-level attacker, but as it stayed on the field with its 3 types of destruction resistance, which were quite hard at the time, its ATK continued to rise due to its own effects, making it an uncontrollable monster. However, it is extremely unreliable as it can pass monster effects, not to mention exclusions and bounces, but even destruction effects.
On top of that, if even one part is missing from his GY, it self-destructs, which is an unbelievable disadvantage of increasing its own vital points.
If the contract to put out this monster can be Special Summon from Deck / GY, if the contract with this monster is Ritual Monster & Ritual Spell, if there is no contract in the first place and if the conditions are met, which monster can self-SS from hand or GY? Or if even one of them corresponds to these, the usability would have been somewhat different.
As I wrote at the beginning, I like monsters as an idea with elements of surprise, so let's add one point.
