Colossal Neutral Vanndar

Hero - Vanndar.

Hero Power - Battle Tactics.

Signature Treasure - For The Alliance!

Your signature treasure will help fill in the gaps or can help you find more large neutrals to discount a larger amount of minions per hero power. Some decent flexibility in picking treasures with lots of legendaries, all neutral minions and a decent amount of battlecries. Crystal Gem is also a very solid pick with being able to hero power on turn 1 and get the discounts rolling.

Marin is great tech against deathrattle hunter as it makes their hero power less reliable and have a chance to give you strong treasures and Malygos will help you draw your discover spells.
