First of all, if it is a PTQ usually you can sign up and they will just assign you partners, which I dont recommend at all. The format is very tricky and difficult with lack of experience. As you would expect there are little tricks as there are in any other format.

I woud suggest you at least find someone you know from a local card shop, friend, relative, or family member that can play well, so that you assure cooperation, as that is the key to a team being successful.

Next, when working on the three decks, dont try to make 3 even decks. The first round or two that might be ok, but later other decks will most likely prevail.

I would suggest one above average deck, an average deck, and a bit below average deck this is the deck that the best player on the team will play, as maybe his luck, karma, and skill will be more likely to push it to the top.

I am not sure if the info is up anymore, but there was last year's Pro Tour New York (I think that was the one?) where Finkel played the worst deck of his team in order to try to pull something out of it.

The key is to have one guy sweep, the next come damn close, and the guy with the worst deck to just stay above 50%.

Most key removal and creatures will go in the better deck.

The second best deck should not share a color combination with the first deck if it all possible because you dont want these two both needing the better cards.

The third deck is the tricky deck, it will be the one running the tricks and combos in order to hopefully pull them off and make things easier. This is the hardest of the three decks to build and by far needs the most attention as hopefull with good card pulls the first two could be built and play by a team of untrained monkeys.

I hope this helps you at least a bit, and good luck.
