Topic: Fire Emblem Awakening DLC Question

I want to buy some of the Fire Emblem Awakening DLC packs before the Eshop gets closed down, but I didn't want to drop $50 to buy all of them. Which ones would you suggest getting if you could only choose three. The packs are
Future Past
Scramble
Challenge
Rogues
Smash
Lost Bloodlines
Golden
Champions

I would prefer ones that may add new characters I could use during the main campaign. Thank you

This might help for a rundown of what each DLC entails:

Just in case you wanted to know firsthand what you'll get for each.
