"Mysterion the Dragon Crown" Rating Score by ねこーら

Comprehensive evaluation: Although it is good as a hindrance to deployment to the race unification Deck, it is difficult to get involved with many holes and your own field.
It requires Spellcaster and Dragon, and the disadvantage is that it weakens by the number of removed cards, so 《Magicalized Fusion》is difficult to use.
However, if you put 《Muddy Mudragon》in his Synchro Summonable Spellcaster Deck, or use 《Keeper of Dragon Magic》with 《Dark Magician》, you can reduce the number of removal cards and make it easier to prepare fusion materials.
The effect is to remove all monsters of the same race as the monster that came out with the monster effect, so it's easy to stick in a unified race Deck.
Even if the races are not unified, one body that has been Special Summoned can definitely be excluded.
However, due to the fact that he has the same race as the monster that activated the effect, his deck cannot use the effect with a deck that uses different races, and the fact that he cannot interfere with Xyz summons is a big disadvantage.
There is also a fear of weakening to involve your own monsters.
I would like to devise a few things such as aligning the races around Rivalry of Warlords and increasing the number of cards removed.
