Here is hybrid build with quite strong plays available in late game while having early game as well. It won't last long with Jades, Evolve, Devolve and Doppelgangster rotating out soon, so enjoy it while you still can.

This one can fight for early game with Jade Claws, removal and early small creatures (especially Fire Fly) evolving, but Jades pack lets you go to the late game with also potential for bigger evolves, into The Lich King, Ysera and so on.

Obviously you can get lucky with evolving 1 mana creatures into Radiant Elemental or Sorcerer's Apprentice with Unstable Evolution, keep in mind abusing this situation requires time, so avoid roping before evolving. There are still free wins with old Doppelgangster+Evolve combo possible, especially if you throw 0 costing Corridor Creeper to the mix.

One more thing to keep in mind - Murmuring Elemental works with every battlecry - not only creatures. So you can play it with Jade Claws and even Thrall, Deathseer - and this combo will evolve all creatures into random ones costing 4 mana more. It won't happen often as it requires 7 mana and some board, but even with few weeklings it's worth it.

Not much planning ahead considering Elementals required, as you will be playing much of these and there is only one Elemental synergy with Kalimos, Primal Lord, but it can be very powerful, especially with Murmuring Elemental. You can end game with Murmuring Elemental+Kalimos, Primal Lord combo, but save your life or clear big board only on opponent's side too. You can use 2 different effects as well. And if Kalimos, Primal Lord happens to survive, you can return it to hand with Grumble, Worldshaker and use his effect again. Remember not to use Invocation of Earth ever.

Grumble, Worldshaker is absolutely insane in this deck. You want to return to your hand battlecry cards likeJade Spirit, Kalimos, Primal Lord, Murmuring Elemental, or even Doppelgangster but It can be also used to heal big Jades, or other, evolved minions. It makes you able to use battlecries of evolved creatures too.

Depending on match-up you can use one of few approaches to the game - either going for early evolves on Fire Fly, Totems, early Jades, punishing opponent's slow start (but beware early mass removal), going on curve growing jades and evolving (beware late mass removal ;)) or going for big comeback, with Corridor Creeper after trades or Volcano which can give you major swing and win games, especially with Evolve following.

Mastering Evolve Shaman is not easy, as it requires quite a good knowledge of card pool, evolving = RNG, but you can help your luck if you know what you want and what you can expect from evolves and devolves on different boards. It's a lot of fun though, as every game is different, which is invaluable in this sad meta.
