Works well against minion based decks. Sadly, Owl OTK seems to be faster. 

Combos:

Multicaster draws at least two cards if you played Windchill + 1 other Nature Spell

Brilliant Macaw is very versatile. You can use it to draw 2 cards, freeze the entire board, chain discover or call upon the power of two elements.

Diligent Notetaker + Windchill

Snowfall Guardian and Bru'kan of the Elements corrupts your 4-cost cards.

Primal Dungeoneer has a huge chance of drawing two cards, since all spells are Nature except for Windchills. You also have 6 elementals in your deck.

3 out of 4 of Brukan's hero power are good stalls.

If you don't know the OTK yet. It's Bolner + Lightning Bloom + Y'Shaarj -> Then APM Use all Dunk Tank to face then Cicrus Medic, Repeat.
