Knight of the Living Dead

A new deck I decided to make since my old white samurai deck is getting so boring. Ever since I layed my eyes on Haakon, I wanted to build a deck starring him. I already had an Ashes of the Fallen so I had a pretty good idea as what I wanted to do. I looked them up for some deck ideas when I stumbled across the ornithopter combo used with Haakon and Ashes. I decided to go with that, and throw in some Hellbent too. I'm thinking I would like to have Gibbering Descent be a main part of this deck, I have yet to get all of the cards and playtest it but skipping your upkeep can be great with the right cards right? It's a great way to stay Hellbent too, any suggestions are more than welcome. I'm not very experienced with building decks and this is only my second one to put together. Again, I am very inexperienced at sideboards so I'm just adding cards I might want in the main deck.
