This deck is all about getting Lurking Sanguar out on the board ASAP. Normally you'll aim to play one unit on your first turn and have a unit with charge ready for your second turn. Keep in mind you can go negative with contracts and still play a 0 cost card. If you draw a god hand you can flood the board with Valks and Sanguars. Just cross your fingers that your opponent doesn't hold any cheap board wipes.
Update: I've removed the Toxic Wisps as they weren't being all that useful, and replaced them with Shadowcreepers to make removal of Aegis units easier, as well as give us an option to discard a card to kill a unit if we get to 5 power. I also replaced the Piercing Griefs, even though they are useful for getting Lurking Sanguar out on the board, I feel it is more valuable to have a unit with lasting presence on the board. I've added Kazuo instead since he gives us another option to play on our first turn, and the option to invoke later in the game can be useful if you don't kill the opponent right away. Overall, I think the deck is in a good place now. The one adjustment you may want to make is add more copies of Syl if you are facing opponents with lots of spells. I had a 70% win rate with this deck over my last 40 games. Most games over in 5-7 turns.
