Alright HearthPwn fam, this is the actually decent Tempo Druid List I've been working on, and it is subject to change.
First off, the idea of the deck is in the name, tempo. Utilizing card synergies like Razormane Battleguard and the plethora of taunts with decent stats, you can get a wide board going early. The ultra-powerful openers you're looking for are turn 2 Razormane Battleguard + Bonechewer Brawler and turn 3 Mark of the Spikeshell into a now activated/corrupted Dreaming Drake. That's 7/8 worth of stats on turn 3 alone if you can pull it off.
Secondly, the inclusions of cards like Kazakus, Golem Shaper, Arbor Up, and the many sticky 5-drops makes for a hard to stop curve. Arbor Up is not so crucial as a finisher, so don't be stingy. You can easily drop it on 2 and even 1existing minion to burst a small amount of extra damage and add board presence.
Then usually by turn 6-7 you've eaten up most removal from your opponent to slam down your finisher, Primordial Protector. The 2x Kindling Elemental's have been added purely to target Primordial Protector making it 7 mana and truly a power turn all-in-one. You also draw Guardian Animals as a result to immediately be able to follow up with more minions to trade away taunts/increase your board presence.
