Well, this deck is based on the power of Infinitrack monsters of mixing their levels with other Machine cards basically. Sadly, Zombie World deck is one of the main counters to this deck strategy because it makes all the cards turn into Zombie monsters.
I usually use Urgent Schedule as soon as possible to bring Super Express Bullet Train and Infinitrack Harvester, then link Infinitrack Goliath using Harvester in order to send it to the graveyard and use Infinitrack Trencher on my Graveyard (if able) to bring back Infinitrack Harvester and use its effect to mix its level with Super Express Bullet Train and get 2 level 12 monsters to XYZ summon Number 77: Seven Sins, or ZEUS, but I prefer Seven Sins because Zeus is easier to summon just by using a low rank XYZ monster like Gear X Gigant.
Also we can use Machine Duplication to multiply the number of Harvesters instead of sending it to the Graveyard, in order to have more monsters to tribute and activate effects. There are many strategies to play in this deck, but I will let you find them out. (I need to work so I can't stay for long writing, sorry).
