Don't keep Fire Plum Harbinger if you don't have many elementals in your hand. If you have a lot of Jade cards in your hand, work for that, if you have a lot of elementals in your hand, and you seen you can get a nice reduced curve out, then don't try to mulligan for jade cards. There are two paths to start the game. You can grab jade claws, jade spirit, and maybe a board clear, lightning bolt, or Fire fly. Just try to get your golems big and hold board control. The other path you can take is to plop down a bunch of elementals, hopefully a turn earlier than they would normally come out. You would want to be holding Fire Fly, Fire Plume Harbinger, Hot Spring Guardian/Tar Creeper, and Servant of Kalimos You want to play Firefly turn 1, Harbinger turn 2, then a Hot Spring Guardian/Tar Creeper, then drop Servant of Kalimos on 4. Keeping the train of elementals up so you don't need to worry having to wait a turn to trigger Kalimos or his servant.
The best (or worst) of both worlds. Using the ever powerful jade golems and implementing the elementals, I feel that this deck is really powerful, being able to live against aggro yet still finish out like a midrange deck. Playing this deck reminds me of early dragon priest with the fire elementals.
