Zombie Tribal, with devotion as an underlying objective (thanks Gary!), is what this deck is all about. A handul of Lords (or Lord-like creatures - I'm looking at you Metallic Mimic!), along with a horde of low-CMC Zombies, some with nifty abilities of their own (Cryptbreaker/Relentless Dead), all set-up this gameplan nicely, quickly building-up to the ultimate goal of slamming a massively devoted Gary (aka: Gray Merchant of Asphodel) for a big swing in life-totals (especially in multiplayer!...which is what this deck was built for btw). A fatal swing if all goes according to plan.
The Whip of Erebos is in there for not only the Lifelink, but for bringing dudes back, particularly Gary (for his ETB effect, obviously).
I added some card draw for consistency, like Sign in Blood and Foulmire Knight.
Bontu's Last Reckoning is in there as a last ditch effort/back-up plan to stabilize/reset in multiplayer matches that get out-of-hand.
This deck is extremely vulnerable to flying, as it has none, and this coupled with having barely any removal, things could go south pretty quickly. Therefore, I thought adding a few Gift of Orzhova could help a bit in this regard (not to mention it adds to devotion!), as well as a few Murderous Rider.
In any case, seasoned necromancers and new gravediggers alike will have fun with this one!
