Check out this INSANE 45 damage OTK Naga Hunter deck. I used this deck to go 10-2 at Legend! I wanted to build a deck around the new Celestial Shot in the Titans mini set. I started by adding Celestial Shot and Twinbow Terrorcoil to the standard Arcane Hunter deck. However, it turns out that when you use Twinbow Terrorcoil to double cast Celestial Shot the first Celestial Shot buffs the second Celestial Shot and then they both buff the next spell. So I decided to see what the biggest OTK combo I could build was.
So I built the OTK Naga Hunter deck and replaced the secret tech with nagas. Crushclaw Enforcer to help with draw, Rainbow Glowscale for spell power buffs and Murkwater Scribe to discount spells to pull off bigger combos. I also added Queen Azshara to get Ring of Tides to get us another Celestial Shot for 1 mana.
The full combo is Twinbow Terrorcoil and a Murkwater Scribe on the set up turn. Followed by Celestial Shot then the secondTwinbow Terrorcoil followed by another Celestial Shot then you finish them off with Arcane Shot.
Depending on the amount of boosted spell power, this combo does between 40 and 50 damage. Check out this video where I play the deck and show a 39 and 45 damage OTK combo!
