You can either play Shaman with Elementals or with Jades. Both are doing well on the ladder, but Jade Shaman has a slightly higher winrate.
There are two Bloodlust spells in this deck -- one for a solid board clear, and another for finishing the match-up with a lethal blow to your opponent’s face.
If card draw is more important to you than extra damage, then consider replacing one Bloodlust with the second Mana Tide Totem. It really depends on your playstyle and what you want to achieve with this deck.
