Curse of Naxxramas Ep32 - Heroic Grobbulus

This might be the toughest boss of Naxx to date.

Heroic Grobbulus has a great AoE hero power (better than Consecration and it's free), truly annoying minions and the best single-target buff in the game (+4/+4 and taunt for 3 mana). His big weakness however is that he lacks single-target removal. This looks like a job for... Gimmick Priest!!!

Lightwells and Deathlords will be your go-to minions as you buff them to ridiculous size and keep them healed. You'll eventually mire through his taunts and hit for massive damage.
