Iron Chain Garden

Iron Chain Repairman revives Iron Chain Coil to make level 7 synchros. Send Iron Chain Coil to the graveyard with Scrap Recycler to set up Iron Chain Repairman plays. Because this deck can summon Ancient Fairy Dragon, I added the field spells Geartown and Black Garden to take full advantage of the dragon's effects. Geartown summons the powerful Ancient Gear Gadjiltron Dragon when destroyed and Black Garden's revival effect can be used with Summoner Monk, Breaker the Magical Warrior, and Iron Chain Repairman.

Some Tips

Two Treacherous Trap Holes are used because the benefits of drawing 1 outweigh the chance of drawing another in the same match.

Summoner Monk can summon Snipe Hunter and Thunder King Rai-Oh from the deck.

Drill Synchron is a level 3 machine tuner that can be used with both Black Garden and Scrap Recycler. It can also summon Drill Warrior, whose direct attacks and monster recycling effect pressure passive decks.

Ancient Gear Engineer is a level 5 monster that dismantles backrow and is searchable with Geartown and Giant Rat. Ancient Gear Engineer + a level 3 tuner makes Stardust Dragon.

Forbidden Chalice is a flexible card that can negate the opponent's monster effects or boost your own monsters' attack. In this deck, Forbidden Chalice most notably counters Caius the Shadow Monarch and Vanity's Fiend, whose boosted attacks are still lower than Ancient Gear Gadjiltron Dragon's stats.
