I do not understand the massive discussion here on this... Many have mentioned how the community is great. Well, do not be afraid to borrow cards or proxy. That way the vets with most of the stuff can help the new players and the new players can test drive.
It is how the community grows. And it takes both sides (new and old players) to make it work. And it benefits everyone.
I have an average amount of content but when I am eyeing a new list I seek out individual cards on ebay. The stuff I have not used for a while I sell. Money is not too tight so I cannot complain but it is not unreasonable to think you can put $200 into this game and keep buying and selling as the meta changes and not spend too much at all. And that is not even accounting for borrowing or proxy.
I tell new players to think about the cost of Magic, Warhammer, even Pokemon TCG and dwarf that to get your x-wing cost lol
