Where would one get Legendaries like the angels and Inquisitor Magnus?

I notice a lot of legendaries list they are from "Extended Set" what does that mean? Are they still avaliable for in any of the packs/boxes?

 

you get a chance of adquiring them (5%) when buying extended packs/boxes.

Personally, I would like if the theme deck pool increased including most legendaries on them.

 

In the Marketplace tab on the site you can buy Extended Set packs or boxes. Each pack has a 5% chance of containing a legendary rune.

 

Thanks, just bought a box and got 2 nice legendaries from it. One of which I had really been wanting

 

I only got the guaranteed exotic in the last box I opened.

 

Same here.

 

2 legendaries from a box? I have bought 2, and zero LEG runes.
I've had to get all of mine from Poxbox.
