if you're looking for a crazy fun deck then look no further than Celestial Alignment C'thun Druid or Celeste McThun

It might be on the meme level of viability, but I promise you will have some crazy fun moments that will make it worthwhile. 

It's also not terrible - we are sitting at 50% winrate after 10 games so certainly not bad

I've created a video guide to help with things like mulligans, win conditions, strategies and combos as well as my overall verdict of the deck

Enjoy
