This deck is a mix of different stuff I threw together. I wanted a deck that was flexiable, but also could incorperate Deck Devastation Virus into it. It's only at 1 copy in Goat Format, but even a single copy can be seriously oppressive if used right, it can practially swing matches if the wrong deck has to deal with it. So how do we do that? We can play a regular boring Dark Aggro deck, or we can be a little bit more creative...
So I just mixed Gravekeepers in. You get a lot more targets for Virus, you get a amazing deck searcher with Cat of Omen, you get Warrior synergy, you get Chaos completely shut down, etc etc. Generally this plays like a Warrior deck; it's lean, aggressive, and can shift gears when needed, going from big monsters to stuff you want to set and search off. We also have Mask of Darkness in case we need to reuse any big traps already used, though it does need Necrovalley off the field to do so it's kept at a sensible 1. Other than that, the monsters are pretty conventional.
Spells search stuff well. Terraforming isn't really used a whole lot but with 3 Necrovalley it helps to be able to get copies faster so you can get the full experience, especially for the Virus strat. Trunade of course cleans up stuff when needed for Spear pushes.
Traps aren't really abused much here suprisingly. It's mostly just generic staples and protection.
Side deck is built for a wide assortment of needs, either for Nobleman counters, Scapegoat issues, mirror matches with Pitch-Black, removal, etc. Not much else to say. If the main plan of the deck doesn't work you can just easily side out into just a Gravekeeper Warrior deck lol.
