Ive been very interested in using
The Scarab God and this looks really awesome and scary! My first deck was a blue/black zombie and I loved it so much. This looks way more terrifying though. Here is my only two cents regarding bettering your crazy token spam!
Enchantment:
Endless Ranks of the Dead - creates a continual flow of zombies to be able to keep up
The Scarab God's ability of draining
Creature: Vengeful Pharoah - This guy is an almost must because of how persistant and annoying he is. Also useful with the scry ability with
The Scarab God so he doesnt HAVE to be on the top.
Best of luck!
