Consistently set up borreload savage dragon with 2 negates, heraldic heavenly spheres with one interruption, and the buster lock. Lock your opponent out the first turn, the second turn go into hot red abyss (and bane if you want), and any links. Flash and DNA could be taken out for more meta cards but this works very well for me even against top decks. DNA surgery is clutch when you have to use buster dragon to make hot red so you don't lose it at the end of the turn.
Main weaknesses: dark ruler no more, mystic mine, nibiru
Barring borrel savage, the whole deck is budget-friendly at about $100. That being said, Borreload Savage is necessary. Buster will lock out all monsters, and barrel load savage is needed to prevent any big s/t plays.
