Games : High-damage combos from hand for each class

What are the 10+ damage combos (or single cards) that each class can play entirely from hand (with nothing on the board)

I know now that Force of Nature + Savage Roar for 14 damage from Druid is fairly common, and other cards could be added to that to increase the damage. I've also seen Pyroblast or 2x Fireball from Mage and Grommash Hellscream + some damage source (whirlwind, cruel taskmaster, inner rage) from Warrior. There's some pretty high damage combos available to Rogue as well with Tinker's Sharpsword Oil and Blade Flurry.
