This is not one of my best decks, but a fun one nevertheless. Using no meta cards, this deck relies entirely on the luck of a coin flip! If you call right, pop a card! If you call wrong, well, lets talk about that later!
Use the monstrous, mechanical dragons known as Desperado Barrel Dragon, Barrel Dragon and Blowback Dragon to blast your opponents cards off the board, but remember, you must believe in your coin to get you the best hits! Even if you do get a tripe Tails, you can use Proton Blast in the GY to make all your results Heads. It's not cheating if it's written on the card!
Other than the Barrel Dragons, you also have Arcana Force EX - The Dark Ruler, who will be a 4000 ATK beatstick once you get three monsters on the field, flip a coin and see what upgrade you can get on him! Alongside Arcana, you also have JINZO The Machine Menace, alongside his trusty sidekick Returner. Jinzo The Machine Menance will special summon himself as a 2400 ATK monster while a trap is in the GY or face up on the field (not a Quick Effect). He can whenever tribute himself to rid all traps on the field and summon Returner, who when destroyed will summon Machine Menace again from the GY, but only for a turn, so use him wisely!
You also have cards like BM-4 Spider who can destroy an opponents monster and inflict burn damage, along with the old Blast Sphere that can do similar work. The mini Twin-Barrel Dragon can pop a card if it tosses two Heads. Keeper and Prisma help to get your Gatling Dragon on the field, Keeper can also summon a Barrel Dragon or Blowback from the Deck, but only in facedown defence position, flip him back up the next turn to activate his effect! Fusion Deployment is a free Barrel or Blowback Dragon from the Deck. Heavy Metal Raiders will upgrade your Barrel Dragons considerably, protecting them and boosting their ATK, while also summoning more Dark Machines! Limiter Removal will double your Barrel Dragons up to 5600 ATK (not permanent).
Mirror Force is a classic way of protecting your board, and Call of The Haunted is yet another classic that brings back anything from the GY!
This isn't a great deck, but it is fun and nostalgic. Good luck!
