I did some Googling and these are the block sizes I got (they vary by region so these are approximate):
Dream Team: 6,789
Animal Crossing: 6,336
Pokemon X or Y: 14,000
total: 27,125
Each block is 128KB. So that's roughly 3.3 GB. I don't know how much of the card is already used by the system. If you want to go digital (for more games in the future), you'll need to get a larger card for sure.
