Hello! My name is Villms and this is the deck I primarily used to climb through Diamond 5 to Legend. Most of my matchups were against Zoo Warlock and Control Warrior, and I think this deck offers a good blend at handling both decks, as well as those pesky Miracle Rogues and Face Hunters.

Mulligan:

Versus Zoo Warlock I always seek out Shieldearer, Equality, Wild Pyromancer, Aldor Peacekeeper, Earthen Ring Farseer, and Consecration. Sometimes I'll keep a Chillwind Yeti or a Sen'jin Sheldmaster if I am on coin and the rest of my hand is pretty bad. You can lose this matchup from them curving out perfectly, so don't freak out. Just need to survive the first 5-6 turns. 

Versus Control Warrior I look to get Chillwind Yeti, Azure Drake, Senjin Shieldmaster, Truesilver Champion, and Earthen Ring Farseer. This deck has too many "medium" threats the warrior can't easily remove, so eventually they will run out of removal and you will have a good board they can't clear. So I mulligan for those early 4 mana threats to get them on their backfoot as early as possible. 

If this decklist gets some traction I'll post more detailed descriptions of my matchups and card choices! Happy climbing.
