I want to pull off using Splitting Axe but so far not much luck.
I've come up with something that's had some mild success in standard. 60% win rate after 25 games around rank 8. Feels about as tight as it's going to get. Can't imagine any replacements being better than what's in this list.
Your basically only win condition is to build a board of a ton of low attack high health minions that the opponent doesn't have the attack points to clear, which you then use to bloodlust the hell out of them.
