Alright guys, this deck is in termoil. It needs help. The main focus on this deck (aside from being a modern deck) is getting out zombie tokens. Lots of them. Besides that, it's got mostly zombie creatures to stall the opponent, some to power them up, but either way it is to stall until I get the mana to unleash the tokens. That's why I threw some green in here, to help get out mana faster so I'm not stalling as much and I can make this deck quicker, and obviously for parallel lives.

Does this deck need blue for token support? I have several dual black/blue lands but I would prefer to stick to two colors.

And before any of you say anything, yes I am aware of death baron, zombie commander, gravecrawler, birds of paradise, etc. I mainly want opinions on how I can improve this deck without buying cards that are 10 dollars or more. I'd like to keep this deck price below 100 dollars. Thanks for any help.
