This deck is mostly focused around the "Infinitrack" Archetype and Earth/Machine Monsters that will allow you to OTK your opponent if you go second, so keep in mind that cards like System Down can easily end this deck if you go first.
This deck's boss monsters are Superdreadnought Rail Cannon Gustav Max, Superdreadnought Rail Cannon Juggernaut Liebe and Infinitrack Fortress Megaclops, but all the extra deck will allow you to adapt to different types of opponents.
Most of the cards on this deck may start a combo, but for this deck's full potential using Infinitrack Brutal Dozer to special summon from your deck any Infinitrack monster in defense position with its effects negated, so Infinitrack Trencher or Infinitrack Tunneller are ideal targets for you to XYZ Summon Infinitrack River Stormer and search for cards that you can extend your field; You can also use Infinitrack Anchor Drill's Effect to bring any earth machine monsters, being Infinitrack Harvester and Machina Metalcruncher the most ideal targets. Don't Waste Anchor drills effect on cards like Heavy freight Train Derricrane, Super Express Bullet train, since those two cards can be special summoned from your hand granted you normal or special any other earth machine or your field only has earth machine monsters.
All machina Cards are mostly support for the deck, Fortress giving you potential to discard cards and Citadel being able to return from the graveyard to help in the field as a monster by itself capable of destryoing cards or as material for any of your Rank 10 XYZ Summons which can turn into Superdreadnougt Rail Cannon Juggernaut Liebe.
Revolving switchyard will help you discard monsters like Infinitrack Tunneller, Infinitrack Trencher or Machina Citadel, since those cards are more usefull in the graveyard than in your hand or field.
Infinitrack Tunneller and Machina Overdrive will allow you to shuffle many of cards that are Banished or in your graveyard and allow you to draw more cards to help you win the Duel, but try not to return all your Infinitrack Xyz monsters, Super express Bullet train, Machina Citadel, Machina Fortress or Heavy freight Train Derricrane, since those cards are usefull in the graveyard or can be brought back with Double Headed Anger Knuckle.
Infinitrack Goliath will allow you to send to the graveyard any Infinitrack monster on the field and then revive any of your Infinitrack XYZ monster on the graveyard will also making it indestructible by card effects as long as it is attached as material to it.
Ancient Gear Ballista will not only help you to search for Ancient Gear Box to activate its effect, but you can also use it to trigger any destruction related effect, like Machina Citadel while its in your graveyard.
Even though Infinitrack Fortress Megaclops is a boss monster in this deck, you will not be able to bring it always since it requieres either a near perfect starting hand a long duel or using Maxx "C"'s effect to draw more cards. But if you're looking forward to doing so, the best way is having already having Ifninitrack River Stormer and any other XYZ monster on the field and using Outrigger extension to turn River Stormer (after using its search effect) into Infinitrack Mountain Smasher, activate its effect to send River stormer into the graveyard, then activate infinitrack Trencher's effect in the graveyard to special summon any Level 5 or Lower infinitrack monster in your graveyard, which will be used to special summon from the extradeck Infinitrack Goliath, allowing you to revive River Stormer.
Try to use Heavy freight Train Derricrane as your go to material for Rank 10 Xyz summons since, detatching it will not only allow you to activate the xyz monster's effect but it will activate its own effect, allowing you to destroy any card on the field, which is really helpfull if your opponent is using floodgates like skill drain and you dont have Feather Duster in your hand.
