The goal is to setup the field with some negates (Naturia Beast / Gorgonic Guardian) and fill the grave with Magnet Warriors. In the second turn you can destroy your opponent’s field with Berserkion and attack for game.
The Low-Level-Magnets are used for setup, Link- and XYZ-material. The Adamancipators are starters and extenders to get more monsters on field and enable Synchro-plays.
Epsilon and Delta do nothing first turn without other extenders, so I choose to play a minimum of them. We want to special them with the Electromagnets or the Adamancipators.
Doki Doki can be a great starter/extender, but is vulnerable to nearly every handtrap. In this build it can be a nice bonus, but is not necessary for the main combos.
I cut the Normal-Magnet-Warriors, Valkyrion and Imperion, because they mostly brick in hand. So we have more consistency and space for non-combo-cards.
The archetype‘s spells help us float the board with more Magnet Warriors from the deck or grave. Both need a Lvl 4 or lower earth-rock (Magnet-Warrior-)monster and also give us some protection. The reborn-cards and Reasoning are options to get the required rock-monster on the field without using the normal summon.
Transmodify works as a toolbox for further combos or additional disruption by transforming any Lvl-3-Magnet-Warrior to an Epsilon (that reborns the tributed monster), an Analyzer (wich is a tuner and does Adamancipator-things), the Barrier Statue (that locks both players into Earths) or one more lvl-4-Monster für XYZ-Plays.
The other spells and (hand-)traps are for removal, protection and disruption and can be changed depending on matchup, preferences or budget.
Extra Deck:
In general you can play whatever you want. Even if we can spam out lots of monsters, we never get locked into one specific type or attribute (only with our own Barrier Statue).
I recommend playing the Gorgonic Guardian, Grampulse, Gallant Granite, Missus Radiant, Knightmare Phoenix & Unicorn, Naturia Beast and Adamancipator Risen – Raptide.
The Side Deck shows some options for cards that work pretty well with the strategy. Gozen Match and Rivalry don’t restrict the deck too much, although a generic Link2-Rock Monster is still missing in the game.
Torrential Tribute also synergizes with the „Tribute“-effect of the Electromagnets in the opponent’s turn, so we can clear the board and still have monsters on our side of the field.
