This deck also includes 2x Moonglade Portal, which is not in the TappedOut database yet.
I packed Y'Shaarj, Rage Unbound and Fandral Staghelm within two days of each other, so naturally I had to find the best way to abuse them. This deck tries to go as over-the-top as humanly possible, with some early game interaction for faster matchups. Fandral just gets disgusting with Nourish.
Wild Growth, Innervate, Mire Keeper, and Nourish are cards you always want in your opening hand. Against Priest, Warrior, Rogue, and Druid, I recommend hard-mulliganing for these pieces. Against Shaman, Warlock, and Hunter, which are often more aggressive, Living Roots, Wrath, and Swipe should be kept as well. Mage and Paladin are a toss-up, and it usually depends on the quality of the rest of my hand.
I often find myself using the first Nourish of a game to ramp and the second to draw 3 and refuel.
Seems like you have a great strategy but then dont do cool stuff with it. North Sea Kraken, Druid of the Claw, and Chromaggus are definitely doing important things, but it seems like it would be better to add in high-cost value cards to hit with YShaarj, like the Lich king and ysera. These suggestions are also probably preferable to your current set since they dont have Battlecry effects to be cancelled with YShaarj. However, Im new to hearthstone, and have no idea what the legalities are, so these are probably not standard legal, which is the set you have selected for this deck.
