So after reviewing everyone’s suggestions, this is the updated one. I decided to keep some of my spells to take out some bigger minions while retaining board control, kept explosive shot to try and counter some token druid. Again, any advice on the original or updated would be greatly appreciated! Thank you again.

Hi! I’m fairly new to the game (started in october 2018). I’m looking for some advice for which cards to place in my Deathrattle Mech Hunter deck. I’m primarily having trouble with token druid or khadgar summoning mage. Thanks for suggestions
