"Rainbow Dark Dragon" Rating Score by ねこーら

Comprehensive evaluation: In addition to being able to use [DARK], unique moves such as being able to use [Advanced Dark] to use Crystal Beast are also possible.
You need 7 types of DARK, but it's not too difficult to secure 7 types if you have a lot of types like Rokket or use a lot of Link Monsters.
However, since the number of GY cards is extremely reduced, it will be difficult to move after that, and it will be quite painful if I can't finish it.
Self-enhancement is quite unwieldy unless you remove all the other monsters on the field, is there a chance to use it?
If you destroy Doomsday Horror and return the 7 types that were removed to his GY, you can strengthen it to 8000, but is it close to Roman Cannon?
On the other hand, [Crystal Beast] has Ultimate Jewel God Support and can search for 《Advanced Dark》, so this card can also be included.
The condition of 7 types is also a unique merit that can be produced even if the number of Crystal Beasts in Field GY exceeds 7 types by mixing Advanced Crystal Beasts and normal Crystal Beasts.
The self-enhancement effect is difficult to use, but if you replace him with Rainbow Overdragon and exclude him from GY, you can enhance it to around 5500.
Or is it possible to ignore the summoning conditions with "Rainbow Gravity", and with "Advanced Dark" he removes the 7 types of Crystal Beasts that have become DARK and he attacks with ATK 7500?
