Mulligan: Innervate , Dreamway Guardians , Power of the Wild , Keeper Stalladris , Wrath , Lifeweaver .
Guide: Try to generate with Keeper Stalladris spells. Over the game you should try to control the board by choosing mostly of the time Power of the Wild (the 3/2 minion) and keep 0 mana spells as long as you can until you get the Exotic Mountseller on the board.
She will generates 3-mana cost beasts. You can then buff these minions by simply using Savage Roar , Cenarius , Cenarius or Power of the Wild.
Just try it out and find some ways. It tooked some time for me until i get the exact playstyle of this deck.
And now, have fun and good luck
Thank you for your time!
