Awesome question, Warrior!

Once you reach a warzone that has Heroic cards, you can start earning them just like the other cards, but with a much lower chance. Heroic cards are really rare, but in due time you can earn one!

Also, keep an eye out for special offers and prizes that may contain a Heroic card.

Here's a list of Heroic Cards:
