"Magician of Black Chaos MAX" Rating Score by とき

Magician of Black Chaos is chaos MAX. With chaos in his original name, he seems more natural in his name than in Blue-Eyed.
It has the effect of blocking the activation of the opponent's monster effect by releasing your own monster when you succeed in Special Summon, and the effect of recovering his spell of his GY when destroying the opponent's monster in battle.
The first effect can be used not only for ritual summons, but releasing a single monster is expensive. As for deterring the activation of the effect, the only thing you can do is pass the attack safely during the ritual summons. It would be interesting to revive during the opponent's turn with something like Rebide, then release yourself to restrain the opponent's development.
The second effect is simply that his GY Spell is still not allowed to touch or requires a combat destruction. Although there is a hit point of the highest level class, it is not always possible to activate it, so the stability is greatly reduced.
In his deck with Magician of Chaos, would that effect make him a top card to Special Summon? However, even so, it is also a card that is unsatisfactory as a top-level ritual.
