Jötun Grunt is a great piece of work. 4/4 for 2, and your opponent wont be happy to use his yawgwill with this in play.
I havent tested it, but I will do so soon.
you deck looks good guli, but for me I have never used negators succesfully. red is big in my metagame, and the negator is suicide when I use it in a deck

but against other decks its great, first turn ritual and negator can win games.
you do have a lot of discard. dont get me wrong, discard is great,but sometimes when further in the game, and your both waiting to topdeck that wincard, you dont want to draw another hymn or cabal.
