Using the Azathoth Expansion with Sleeper Faction in Cthulhu Wars!

Hey everyone, I’ll be honest, I’m not a huge fan of most of the azathoth expansion content with Sleeper, the faction needs most of its content so its hard to give up anything. The biggest advantage is recruiting monsters and getting free ones into your pool, but that applies to any monsters from any neutral box. I’m curious what master strategies some of you will provide, please help me catch what I missed!

I “am” excited about using Star Vampires with Sleeper, or bashing people with an Azathoth at the end of the round, but Sleeper has so many power issues I just don’t know if its possible to get it out without crippling yourself.
