The basic goal is to summon/spam as many normal gadget monsters as possible as quickly as possible. Summoning Platinum Gadget and Gear Gigant X to summon/search out more gadgets. Boot-up Corporal in combination with gear charge and Machine duplication can also do well to spam out/recover gadgets from the GY. Topologic Bomber/Trisbaena can also be used as disrupting/field nukes, should things go south, with the trap monsters being good triggers for them, especially Bomber dragons effect.
This deck is very weak to Anti-Meta cards, such as banishing/anti-special summoning, do be weary of cards such as Macro cosmos.
Add spot removal as you wish.
