Race/Class/Mojo/Power Question When Mixing Classic and Zombie Decks

[odel0022]

I know the "house" always make the rules, but curious about how others mix Zombie Munchkin in with the standard race/class deck of Munchkin.

When playing with a mixed deck like this, are you allowed to have a Class, Race, Mojo, and powers (powers can be added together to not exceed your level)? I.E - Can you be a Fast, Atomic Zombie that is an Elf Warrior?

Or do you choose whether you want to just use the class/race combo or mojo/power combo. I.E You would choose to either me a Elf Warrior or a Fast Atomic Zombie

Hope that makes sense.
