"Malefic Red-Eyes Black Dragon (Updated from: Malefic Red-Eyes B. Dragon)" Rating Score by ねおんちゃん

Is this Sin? No, it's Red-Eyes' valuable deployment power.
If you try to use it with Sin, there is honestly no way to use it other than making it a synchro material by taking advantage of the only ☆ 7 point. On top of inheriting the really terrible stats from Red-Eyes Black Dragon, it doesn't have any effect to replace it, and in the end, it can't even be trash unless you have a dedicated construction with Red-Eyes Black Dragon in the main deck. It cannot be used without inserting the card. No matter how you look at it, it's too weak, definitely the weakest Sin monster.
However, the only Red-Eyes that have the effect of actively Special Summoning themselves are this, Redame, Sub-Black Dragon (MD not implemented), and Black Star Dragon (MD not implemented), both of which can be searched from Black Steel Dragon. In that sense, this card, which is said to be the weakest in Sin, is also very useful when turning Red-Eyes as a 7-Axis Xyz Deck or Link Deck.
Especially in the Master Duel environment, neither Akokuryu, whose illustration is the late Takahashi-sensei, nor Kuroseiryu, which is due to the timing, are not implemented, so his Red-Eyes is the only one that can be Special Summoned without losing board advantage. It works very well as Or rather, Red-Eyes in the MD environment where I have to cling to such a card, I want to stop it because it's too hard and too weak.
Striker Dragon, who is the top candidate for Link 1 with Black Steel Dragon, can search 《Boot Sector Launch》, and Dragunity Night Romulus, who can play with Black Steel Dragon, can search 《Dragon Ravine》. is easy to secure, and in fact, it is a card that goes well with Red-Eyes-started Dragon Link. It is very good that you can search with Black Steel Dragon and throw it into the field at an appropriate timing.
Red-Eyes I'm doing my best to use it. This obscure card is Ray of Hope for Red-Eyes players.
