The deck idea is strong but I will agree that this deck does have a really high curve to it. There's nothing wrong with having strong cards, but too many will slow down your deck and keep you from making consistent plays. If you want to utilize the zombie and tokens I would encourage you to use regal carcal, even though it is a high drop it will give you 2 tokens which, with the anointed
dead, will give you 4 tokens instead. This being done with only 2 cards is how you get the advantage from your cards.
Drake haven can be a good way to drop multiple tokens per turn while at the same time giving you the embalm tokens to make later (by dropping big creatures in the grave early).
Seeker of insight will give you the discard/draw outlet you need so that you can get to where you need faster. What do you think of these ideas?
