So for a tournament, like list bulding, you choose three obstacles to bring. They can't be the same.

You and your opponent each supply 3 obstacles making 6 like normal and everything is placed as it used to be.

Now here's where I have questions. What if you and your opponent bring the same obstacle? Who replaces? Does this mean you need to bring up to 3 more reserve obstacles?

Nobody replaces. Duplicates are permitted so long as your 3 are unique.

That would make sense. That's whatvi get for reading the obstacle rules under my desk at work.

Read rules under the desk? Thats a novel isea...that is usually where I do my drinking

That would make sense. That's whatvi get for reading the obstacle rules under my desk at work.

Why are you hiding under your desk?

Probably more effective than hiding on top of his desk.

I'm getting a George Costanza picture going on in my head here. Careful with the ticking alarm clock.

Yup, only your 3 obstacles have to be unique to the other two obstacles you bring. Which means there can be 2 big asteroid tokens in the play area.

There cannot be 3 or more big asteroid though because that would require a player bringing a copy of an obstacle token they already selected.

So it is now a lot like squad building. After you make your squad you take the 6 asteroid tokens from the core set, and if you have the 3 debris clouds from the YT-2400 expansion pack and/or the 3 debris clouds from the VT-49 Decimator expansion pack you can place them with the 6 asteroid token. Out of those possible 6/9/12 tokens you may have, you must select 3 of them. If all you have are asteroids from the core set then you are selecting 3 rocks. You cannot include copies of the tokens so say you don't have a YT-2400 but have 2 VT-49 Decimators you can only chose from the three debris clouds tokens from a single VT-49 Decimator pack.
