I thought you get the free random DK heroecard after completing the prologue not after beating the Lichking.

i would like to see pyros in this for obvious reasons. And a blazecaller could get instant value after jaina cause the battle cry should also trigger lifesteal.

The rest seems worth a try.

Elemental Deck seems to be OP

Combines well with the new weapon for Rogue. Because of the low health it is too easy to get rid of imo.
