Indeed, if u wanna counter Gadget Decks u Should run a Chimeratech Deck, everytime ur opponent summons a Gadgets the next turn will have another one in field for sure and thats good for Chimera because while our opponent has more monsters on the field u will cause more damage to him =)...but if u really want to risk and do like in the last 2 Shonen Jumps, Run a Deck that u know that the players can´t counter, for example with the "Chain Burn Deck" anyone was prepare for that kind of deck any card on the side deck was useless against that deck and it was a Top 8 and in this last Shonen Jump, Cyber Stein was gone so everybody take out their Wabokus and their Kuribohs from the side deck and bang!! lots of "Chimeratech Deck"s were in the Shonen Jump plus is a good counter for Gadget Decks, oohh or like that "Cyber Jar Mill Deck" it was a very nice surprise LOL, well that´s my suggestion try something different =)
