Hero Power Mage

Watch Posts are generally good and getting your hero power cards early allows you to power up your Mordresh Fire Eye. Runed orb is just a good card.

Talented Arcanist + Shooting star is good for controlling the board early. Reckless Apprentice is board-wide damage even better if you have played wildfire or fallen hero. Brain Freeze is good cheap single target damage. Runed orb is just good and Cultist is good defense and recovery.
