Mosh'Ogg Enforcer is pretty bad. 2 more health for 2-3  mana is worthless and it'll be never played in most of the games. Zilliax doesn't serve the combo with 2 health and it'll pollute the resurrect pool. Sadly we can't cut Northshire Cleric and Wild Pyromancer because they are the draw engine.

In a long game Seance is preferably for Catrina Muerte. 

This archetype is much more consistent this way.
