This deck's main focus is buffing up Wind-Up Automaton in a non-traditional sense--it's not an automaton deck. In fact, Wind-Up Automaton is the only automaton in the deck! The rest are humans. The main combo comes from Royal Banner. Each time after a non-human attacks, it's countdown is increased by two. Basically, the Wind-up Automaton will have a high CD every turn! And therefore a strong attack each turn!
Some other combos to note: Thought Trap to make Wind-Up even more powerful, and also using Controlled Ligthening to do damage with that high CD!
Lastly, this deck utilizes Lightening Chest to save up energy for that time when you get Melt Iron Shell to really give Wind-Ups the boost. But if not the Wind-Up, Magnetizer is also another great candidate for it!
