Games : Max damage from hand for each class

I was playing a few games on the first day of this new season (happy Raging Ragnaros everybody) and I came up against a Druid. I was playing control Paladin and I kept clearing his guys off the board and dealing moderate damage to his face, which he healed. I took a bit of damage but I was waiting to play Guardian of Kings / Antique Healbot until I had really solidified board control (since I was at 20 health).

Next thing I know he plays Force of Nature -> Savage Roar -> Innervate -> Savage Roar and I die. If I had known about that combo I certainly would have dropped a heal sooner.

So my question is: What is the max damage each class can deal from hand, with nothing on the board?

I'm looking for practical combos that are seen relatively often, not necessarily something like Raging Worgen -> Inner Rage -> Charge. This is just so I know when to prioritize healing / taunting over dropping stronger minions for board control.
