It's just an attempt at BU Zombies. Any suggestions would be helpful and much appreciated.
THE BREAKDOWN:
Bone Splinters: Because we'll always have graveyard retrieval and expendable creatures, it'll be cheap and reliable to pull off.
Cryptbreaker: A strong one drop. Use him early to turn Prized Amalgams and Stitchwing Skaabs into 2/2 zombies then pull them all back when you need them. Strong draw power too if you have a bunch of zombies.
Diregraf Colossus: He can either be a zombie machine or a big body for 3. It really depends on when you want to play him.
Fleshbag Marauder: Use this guy for interrupting your opponents board state. Even better when combined with Nantuko Husk and Relentless Dead for triggers every turn.
Gisa and Geralf: These guys really let you have fun. With them out, don't be afraid of losing someone important. Just make sure they don't go into your graveyard.
Grasp of Darkness: A cheap, lower power removal spell. Less situational than Bone Splinters, but still cheap.
Liliana, The Last Hope: A strong planeswalker that acts as a weak removal spell and graveyard retrieval. Ult-ing them, whenever that happens, it's likely to end most games.
Murder: MORE REMOVAL. More versatile without any restrictions. Just more expensive.
Nagging Thoughts: A cheap card that can be combo-ed with Cryptbreaker to draw cards. Also useful when there's nothing else to do.
Nantuko Husk: Maybe the most valuable card in the deck. We're fine when things die, but not get exiled. And towards late game, it's a nice card to swing big with.
Prized Amalgam: A nice card, as long as it's in the graveyard. Being able to pull 2-3 out on turn 3 or 4 is a nice feeling and get's a nice advantage early on.
Relentless Dead: He's a nice zombie card. He can die all you want and pull anyone back, including himself. The menace adds a bit of removal, but always make sure you can pull him back if need be.
Stitchwing Skaab: A flier that can pull itself back. Nice for triggering Prized Amalgam, especially if you turn 3-4 it for a couple of them.
Westvale Abbey: This is a finisher card that won't see too much use, but is a nice one if you have the option for it.
Zulaport Cutthroat: He's really just here to discourage blocking. Still, a nice 2 drop for when you need it.
