Please rate/fix my Yu-Gi-Oh Machina Gadgets deck. (September 2010 banlist)?

Very good, I like how you managed to get Pot of Dualitys and Solemn Warnings. I think you need more monsters, but I don't know what you should take out in place of them. Scrap Recycler and Chimeratech Fortress Dragon are some good cards.

Extremely Good, I was had just been trying to find a way to fit Dualities into my Machina deck! XD

However: I have found that Cyber Dragon hasn't been a very good card for Machina, mainly because I have no way of removing it from the field and I get raped by CFD. Try out 2 Peacekeepers instead; I've found that they are a lot more consistent (and the union effect is great too :P). But, if Cyber Dragons are consistent and don't lose you games, then go for it.

And no Trunade?

9/10

Its very good, except I highly doubt Machina Force is necessary. It can be a dead draw if you are unlucky. Other than that, I might consider getting Dark Bribe. It is an excellent counter trap that negates and destroys magic and trap, at the cost of your opponent drawing 1 card. Other than that, kudos to an excellent deck.

Monsters -Gale -Gorz -Peace Keepers +Cyber Dragon Spells -My body as a protect +chilly Wave Traps + darkish Bribes/Seven equipment of the Bandit I used to run a Machina device o.ok.deck. With the right hand, you may FKT or OTK. i have run Machina ever because they got here out, so i understand its a danger. solid success with the deck.
