I've seen that there are tournaments of Android: Netrunner.
Regarding data packs, is it necessary to buy all the data packs to have a chance to win those tournaments?
I guess the cards allowed to be played in tournaments are described to players before the tournaments and the constructed decks have to stick to the tournaments rules...
If I stick to the core set of cards, do I have a chance of winning a game against someone who has all the expansions?
