[_] If your answer is yes, you will need an official upgrade card for each upgrade you would like to bring. In case you know already which ships/upgrades you will play for sure, check if they are available in bundles or if some LGS is giving rebate if you buy everything with them. For upgrade cards alone, consider ebay!
I don't go to any tournaments that allow proxied cards.
I don't buy any Rebel ships.
I still win most of the tournaments I attend.
I am not an Armada god.
Having the best build is not a guarantee in winning this game. Having a suboptimal build is not a foregone failure. There's a lot more to this game that the ships and cards you bring to the table.
So, I don't think it's useful to imply to the OP that if he doesn't have certain cards that he shouldn't go to no-proxy tournaments. He should totally go to standard tournaments, because they're fun to play in.
The first few he goes to, he's going to get his rear kicked, but not having the right cards is not going to have anything to do with it. It's going to happen because he's new. Since he's probably going to have his rear kicked, he should just bring his funky rebel build and go down in flames with it. Wash, rinse, repeat until he gets better.
Besides, until he has a good number of games under his belt, he's not going to know what's good anyway.
I think you misunderstood my post in full.
OP was asking in reference to upgrade cards, and if he should buy imperial ships (or even multiples of ships) only because he wants some upgrade card from that box. Thats what I was refering to, because I wanted to help a fellow gamer save some bugs.. I just pointed out that there are certain events or locations that require you to have the original cards, and multiples if you want to play them on more then one ship, however there are also certain locations that do not require to do so.. and even if he would like to attend tourneys at some point, that there are ways to get a specific upgrade card (ex. Ebay) other than buying a complete expansion box.
Other than that, gratz to your tourney record ;-)
