Magic Origins has a story mode where you play as a planeswalker and earn some gold.
I played through the whole first story (all battles, all skill matches) and the other planeswalkers are still locked.
What do I need to do to access the other four?
I bought the packs as suggested, I replayed that last guy Iora game, I logged in and off. If there was some hint, I missed it.
I saw people on the Internet lament about the game crashing while playing as Chandra, so I'm pretty sure it's not something that would be unlocked later.

After you bought the packs you need to continue to the deck manager to create a custom deck. With that deck you need to complete a "Battle" game, it doesn't matter if solo or versus.
After that, the other 4 stories are unlocked.
Sadly there's no quest log, so you have to pay attention to what the annoying tutorial says.
