There are plenty of brilliant decks in Yu-Gi-Oh Master Duel that the player can choose from. There are enough options that players can lean into their specific playstyle or the archetypes they admire the most. Plenty of Yu-Gi-Oh players love the machine type and like to build their decks around that. Players also love to create the best decks from the anime, which is understandable considering it's where a lot of the game's popularity comes from.
Yu-Gi-Oh Master Duel features over 10,000 cards from the OCG, so players have got enough to build a few distinct machine decks. This freedom of choice is one of the reasons the game has been so successful and enjoys a solid player base years after release. The players who want a machine deck to use are focused on quick gameplay and relying on lots of summoning chains. Not every machine deck in Yu-Gi-Oh Master Duel isn't built equally, so players want to stick to the best options.
6 Superheavy Samurai
The Superheavy Samurai archetype was released in 2015 and proved fairly popular with Yu-Gi-Oh players that prefer machine cards. To obtain the cards for this deck in Yu-Gi-Oh Master Duel, players will have to open many of the Immovable Samurai packs. Players could choose to throw in some of the best Master Duel hand traps for greater defense.
Players running this deck will want to run mainly monsters with only one or two spell/trap cards in the main deck. They also want the extra deck to have a few Link and Synchro Superheavy Samurai monsters. Master Duel Meta's Superheavy Samurai deck is a good starting point for beginner players.
5 Ancient Gear
Ancient Gear was one of the first machine archetypes and is a fan-favorite, having stood the test of time throughout the game's meta. Despite its age, the Ancient Gear archetype is still strong in meta, particularly the Yu-Gi-Oh Master Duel's meta. To obtain cards for this deck, players need to open the Gargantuan Gears, Shifting Gears, and Dreadnought Advance packs. The Ancient Gear archetype can mix well with Yu-Gi-Oh Master Duel's best staple extra deck monsters.
Players can use the Ancient Gear deck built by the YouTuber Atem. It's a great, solid deck that focuses on getting as many Ancient Gear monsters on the field as popular and overwhelming opponents. The deck is very capable of delivering an OTK.
4 Machina
The Machina archetype debuted in the Yu-Gi-Oh 5Ds era and is a solid machine archetype in the game. Based on getting Machina monsters on the field, in particular Machina Fortress, the deck is focused on controlling the field and overwhelming players. The Machina archetype should be bolstered with some of the best Master Duel staple spell cards.
To build the Machina deck in Yu-Gi-Oh Master Duel, players will have to open the Rapid Aircraft Advancement and Shifting Gears packs. If players are struggling to build their Machina deck or simply want to compare it to other players' builds, they could try the Ex-Zero Machina control deck offered by Game8.
3 Gadget
Another old machine archetype, Gadgets has been around since the beginning of the game. Anime fans will fondly remember how Seto Kaiba would frequently use Gadget Soldier. The Gadget deck by MasterDuelMeta is a great starting point for players looking to use this archetype. The Gadget archetype has some of the most underappreciated effect monster cards.
While Yu-Gi-Oh Master Duel uses a more restricted field than the card game, it is still advisable that players mix their Gadget deck in with Machinas to make it more viable, especially if they're struggling with a solely Gadget-based version. Players can obtain the Gadget cards by opening the Shifting Gears, Champions of Hope, Invaders From Outer Space, Onomatopair-up, and Gargantuan Gears packs.
2 Cyber Dragon
To gain the cards to build a Cyber Dragon deck, players must open the Pearlescent Cyber Dragons, Blazing Fortitude, Natural Selection, and Nebula Cyclone packs. Perhaps the most popular machine archetype in Yu-Gi-Oh's history, Cyber Dragons are an extremely strong archetype, regularly being among the highest tiers of countless tier lists on Yu-Gi-Oh decks on the web.
The same is true on Yu-Gi-Oh Master Duel, with the Cyber Deck archetype being not just one of the best machine decks in the game, but one of the best decks overall. One of the beginner tips for Yu-Gi-Oh Master Duel is to stick to the meta, so building a Cyber Dragon deck early on is a great idea. The Cyber Dragon deck by TeamSamuraiX1 is hands-down the best version, so players should look to build this.
1 Karakuri
The Karakuri archetype went under the radar when it was first released, but has since picked up a lot of players who swear by it when it comes to machine-based decks. While there is plenty of Karakuri deck builds online, Game8's build is one of the best. It's a wacky but fun Yu-Gi-Oh Master Duel deck.
The Karakuri playing style is based on changing the battle position of monsters, both the players' own and their opponents. They have a unique play style and most Karakuri monsters must attack each turn they are on the field. To obtain the cards for this deck on Yu-Gi-Oh Master Duel, players must open the Rapid Aircraft Advancement, Traditions of Trickery, Futuristic Creatures, Gargantuan Gears, and Stardust Ties packs.
