How do you buy cards? I'm a big Gundam fan and I wan to collect the cards in the upcoming game, but from what little I know of the state of CCGs, all the cards for popular games get instantly bought by broccoli-headed streamers and obese scalpers.
I was briefly interested in the One Piece cards and did manage to get a few mainly through luck, but I do want to collect the whole Gundam series which seems like it will take more dedicated effort.
What are the tips and tricks for being able to buy cards?
