Love it. Killing wave with blood artist and a swarm of tokens. Potential awesomeness.
Get rid of Ghost quarter, use doubling chant on doomed traveler/Mausoleum Guard/Geist-honored monk. Combine all that with demonmail hauberk to put them into graveyard and include Mikaeus because he has a rather amazing synergy with Gavony. Outside of that. Too many humans, not enough tokens.
Good solid build you got there. How does it play?
