main combos:terraforming/commandant to get both geartown and necrovalley in hand. set geartown then activate necrovalley, destroying geartown ss-ing gear dragon. locked down gy plus no more mirror force etc, can be quite pain for some decks. more geartown in hand = more gear dragon = more fun. sin stardust mainly for more easy beatdown cos of easy access to field spells. GK stuff i saw mostly only used as tribute/synchro fodder (blow stuff up with arcanite like bth and torrential which stops big gear dragon plays)

anyway i don't know if this is the exact list he used, i had to guess a bit and also mod it for the new format. what do u guys think?
