MechComboHunter?

Combo here is: Missile Launcher + Venomizer + Zilliax.
It will clear bord every turn and heal your hero.
You want to use all 3 in 1 turn so you need to use Galvanizer before this combo turn.
You can use Rush from Zilliax to kill Deathrattle minion that would summon another minion(s).
This is 9/8 minion with Divine shield so it can be hard to clear by your opponent's Spells and Rush/Charge minions.
