I finally came up with the best zombie deck thanks to u guys. tell me what u think?

It may be small but what I see is efficiency in your deck. lots of replacing cards going on here. However due to the smallness of your deck i would through in maybe one or two cards that let you recycle from graveyard to deck. just to be safe. also throw in a a soul rope-"activate when your monster is sent to the graveyard. special summon one level four monster from your deck"
