So apparently there's a trick to Loatheb, just like there was for Maexna. If you have a minion on the board with 1 health, Loatheb will always (at least early on when he has the cards) use his spore spell to kill your 1hp minion and create a spore. I watched someone stream the fight demonstrating the trick and he absolutely ran over Loatheb in 6 or 7 turns.

I started playing hearthstone a while back. Should add me as a friend if anyone remembers me.
