Elemental deck for beating the Lich King

You're gonna need the artificer early on to gain armor, and the spell generation cards to have a steady supply of spells. If you survive to the Frostmourne stage, you need to find a good moment to play Jaina asap (but also stall him enough so that he doesn't do like 17 damage to your face a turn). You're gonna need to have multiple elemental taunts on the table so that even if he kills off one without getting gamage, his souls will attack the rest of them and heal you up.
