So I am currently 13-4 with this deck and decided to share.
It's fairly cheap and easy to use so if you're having any trouble I will write an general guide once we hit 5 upvotes and a more detailed one if we reach 10+.
Ok first things first, while this deck has a lot of early aggro it's main focus is the mid/late game.
The main combo is Il'gynoth in combination with Aldrachi Warblades which deal the lifesteal dmg on your opponent allowing you to deal double the weapon's dmg but should that combo be unavailable you still have a lot of dmg to deal to your opponent while keeping a board presence. Try to set up your Aldrachi Warblades turn 1 and then go all out turn 2 for the win.
Kayn Sunfury is one of the best cards in the deck since ignoring taunts means you can go face.
Another really good in the deck is Felsaber ,while it's ability doesn't allow it to attack before you attack each turn having a 5/6 on the board on turn 4 is really threatening to a lot of decks especially control ones.
Another card I really like/use is Relentless Pursuit since not only you get +4 Attack but you get Immune as well which means you can hit anything without suffering any damage and should you combine it with Aldrachi Warblades you get some HP back.
Aggro Matchup :
Against Aggro matchups I would keep any low mana cards since your goal is to control the board with your minions while going for
Cards to keep : Battlefiend ,Consume Magic ,Demon Companion, Chaos Strike, Satyr Overseer, Intrepid Initiate
Control Matchup :
I usually try to play aggro against match ups like these while keeping my combo pieces for a grand ending. If you open a Skull of Gul'dan you want to keep it most of the times if you can have it's outcast effect ready by turn 6 since drawingIl'gynoth , Relentless Pursuit, Chaos Strike, Twin Slice or Kayn Sunfury can heavily favor your match up.
Cards to keep : Battlefiend, Consume Magic, Demon Companion, Chaos Strike, Spectral Sight, Satyr Overseer, Felsaber, Marrowslicer, Intrepid Initiate
I will try to make a more detailed guide for every class but I need more time to test the deck against the meta since I haven't been
playing a lot lately.
Thanks for all the support and love you show to this deck!
