The goal of this deck is to (mostly) OTK your opponent using Hollow Hound and Always a Bigger Jormungar by hitting three low health enemy minions.

Get a Hollow Hound from your deck - hopefully with a nice discount using the Harpoon Gun - and then buff the Hollow Hound in your hand as good as possible using weird tools like Party Animal or amass some small buffs using Thornmantle Musician. Also play the Castle Kennels if available to have them on the board for the combo turn. Then if your opponent has some low-ish health minions on the board it's go time: play the Hollow Hound, buff it even more as much as you can with all the tools you have and play Always a Bigger Jormungar for the OTK.

The rest of the cards is to help you get to your key cards sooner or keep you alive. :P It was often useful for me to play a copy or one of the two Hollow Hound to give a health buff when dying was the only other option..

This is not a fantastic deck, but it works surprisingly well and I had a lot of fun with it. I hope you do too!
