The Zombie deck would be your best bet. It's easy to learn and use. It's also the most complete structure deck that I've seen. ^^;

Machine re-volt.

Just because I like Machines.

if he's using his own cards, then its whichever has the cards that go nicely with the ones he already has

if this is his first set of cards, then he should get the machine deck, cus its powerful and has awesome spells like power bond and limiter removal

an exceedingly effective decks are shape Mariks and the drag-cohesion decks. If u desire to have your man or woman style of deck i might arise with something exciting like purchase gadget mayhem shape deck and integrate it with a insurrection gadget shape deck. 2 blended strutted decks and %. the cardboard that are the superb.

I would say get machine revolt, because he can get really good machine type magic cards such as limter removal and power bond. plus the machine revolt will have more combos, and can take out your opponent quicker than a zombie deck.

and cyber dragon is really good, also cyber phoenix as well.

i would have to say zombie madness because i think it has a great stragigity and you can win very easily with it... =]
