Forum:Best places to farm

Now that Gree has decided to mess with Las Vegas Stage 1 Mission 1 and it is no longer a reliable source of N cards, what is the new best place to farm for N cards and what is the best place to farm for N+? For N+ I have always done Chicago Stage 1 mission 1 but I don't know how good it is compared to some of the other missions. If anyone can help me it would be much appreciated
