Is this Archetype based around Black Holes realistic and balanced?

[Quzo]

All monsters are Dark Attribute unless otherwise specified. Monster Cards named after types of Black holes have “-“whilst others do not except “Vanquisher” and support cards are named after the parts of a black hole. Also, I need a plausible way to ‘defeat’ (eradicate) a Supermassive Black Hole because that is what will happen towards the end of my fan fiction (even if it is just a theory). Perhaps the “BH Radiation” card which is based on the Hawking Radiation theory and that would make the duel drag on a little. Read and see what you think. Me thinks they need more support to add cards to the Graveyard that they need to stay alive, so if you have any relevant ideas please speak up.

0. Derivatization
Send the Derivative Material Monster that is listed on a Derivative Monster Card from your side of the field to the Graveyard, and Special Summon that Derivative Monster from your Extra Deck.
(New style of monster for Extra Deck; will be explained further if I continue writing my fan fic and post it but basically it's a monster that only requires only 1 material monster for its Special Summon)

In short: "Derivatization is a technique used in chemistry which transforms a chemical compound into a product of similar chemical structure, called a derivative." Example: "Stone Dragon" could become "Ironclad Dragon" as Derivatization is designed to make objects better.
