I was not sure where to ask this, so this seems as good a spot as any. What ship do I have to buy to get Push the limit? Been playing about a month and have only Scum ships right now and have yet to come across it. Also is there anywhere to buy single upgrade cards?

Ebay is a great place to buy singular upgrade cards. Push the limit is also in the A-wing pack and the Imperial aces pack.

Push the Limit (3)
Elite Upgrade
A-Wing Expansion Pack, Imperial Aces Expansion Pack

Check http://geordanr.github.io/xwing/ and goto the card browser section. It doesn't tell you how many are included though

http://xwing-miniatures.wikia.com/wiki/Imperial_Aces_Expansion_Pack says there are 2 included, the a-wing has 1.

For cards like this that are only found on a certain few ships, the ebay price is typically high. In this case, PTL is going for around $7, more for the alt art version.

Thanks for the info. I will look around locally for an A wing since I might be hooked on the ships, but ill check e bay also.
