Early game: Steal a card out of his hand with Mind Vision. I do not recommend starting your hand with Northshire Cleric. Deal with small threats with Holy Smite. Try and coin out a Faerie Dragon early game. In my opinion, Faerie Dragon is the best 2 drop in the game as it can't be targeted by spells or hero powers. Your next play hopefully is to steal 2 more of his cards with a Thoughtsteal.
Mid game: Get a Chillwind Yeti/Sen'jin Shieldmasta out. Excellent 4 drops. Holy Nova comes into play now. Perfect time to deal damage to a minion with your Chillwind Yeti/Sen'jin Shieldmasta and heal up.
Late game: Hopefully you still have some minions on the board as Temple Enforcer and Stormwind Champion are here to buff your minions up. Mind Control is for those big legendaries.
Enjoy the deck!
