I thought about what you said and removed the Spellbender. I still think Subject 9 is much better than Keysmith and should be played to smooth your draws pre-Aluneth.

It’s a flex spot to fight aggro, like Zoo. When they play Keleseth turn 2 a lot of their minions become high health, and this should deal with them or help to kill them with Defile or Hellfire. It could be the 2nd Vulgar Homunculous.
