Rogger Moran won the South American WCQ using Machines...but not the ones you'd expect. Although Geargia are hugely popular, Moran's ticket to the World Championship was actually a much older strategy: Machina Gadgets. His build is somewhat atypical: he played three copies of Red Gadget and Green Gadget, but only two copies of Yellow Gadget. The reason? Ratios, of course! Running less than nine Gadgets means you're less likely to draw into multiples. However, playing more than six means that if you draw into two of the same color, you won't have made two of your monsters useless. A total of eight Gadgets gave Moran the best of both worlds.
Twelve of Moran's monsters grab a card from the deck when they're Summoned. After resolving a Gadget effect Moran would have a steady stream of Machines: an army of self-replacing monsters that slowly work away at his opponent's defenses. A single Gadget isn't much of a threat, but when paired with Tin Goldfish they become Rank 4 Xyz Monsters. When Rank 4s aren't enough, Machina Fortress and Redox, Dragon Ruler of Boulders overlay for Rank 7's like Mecha Phantom Beast Dracossack and Number 11: Big Eye. There's slightly more Extra Deck variation in Moran's Machina Gadgets than in Geargia, and that versatility makes this strategy much more robust.
Machina Fortress is a serious threat this format, since few decks have immediate outs to it that don't trigger one of its two abilities. Targeting it with a monster effect or destroying it in battle will cost your opponent a card from their hand or their field, but leaving it around is often out of the question. What's more is that Fortress rarely stays down for long, and can quickly return to the field to continue leading offensive plays. With Geargiagear's upcoming Limitation Machina Gadgets could start seeing more play. After all, Moran has already proven that this deck can win major tournaments. It's well worth considering for both the upcoming North American WCQ, and for the format after.
