Post comments and i will try and answer them. 

Used deck from diamond 3 to legend  62% win rate 33 wins 20 losses

Spirit of the frog with your 12 spells and the coin when second is your draw engine.

Boggspine knuckles is key for your deck. Combined with hoard pillager, evolve and shudderwock as a last resort deck has 9/10 mass evolves to help overcome board clears from your opponent.

Two healing rains are included to help you survive versus aggro but sometimes it is not enough especially if you do not draw them. Sometimes you get random taunts from evolving which helps

Some cards are optional and can be changed depending on what your facing in the meta.

I included eater of secrets due to  facing too many secret mages. When you play shudderwock it also procs the same battlecry.

Also i added stone hill defender for some taunt but you could also try antique heal bot for extra healing or weapon removal.

I do not pilot the deck the best.

Generally mulligan for sludge slurper, desert hair and evolve combo, Also serpentshrine portal is good and spirit of the frog with mutate for draw engine especially when 2nd with coin. Boggspine knuckles in opening hand can also be fine. Also depends on what your facing too.

Deck has a chance versus most decks in the meta. Evolve has a lot of randomness which can both win and lose games but fun to play in my opinion

Good luck and have fun
