Was experimenting with Spell Druid and this list seemed to work pretty well for me. The winrate of 60% is not very spectacular but consider that I'm almost only facing tier 1 or 2 meta decks, even at rank 15000.
The only minion in this deck is the Nordrassil Druid (if you don't count C'thun), this card seems to be overlooked in the current expansion but with this deck she can provide a lot of value, effectively being a 1 mana 3/5 in a lot of games. The best way to use her is to combine her with Fungal Fortunes to draw cards or Feral Rage to gain armor/attack. Other than that she's useful to gain some tempo while ramping up with Wild Growth or Overgrowth.
The goal of this deck is to ramp fast and then play your spells as efficiently as possible depending on the matchup. Against aggro you protect your face and against control you generate value.
Have fun and let me know what you think!
