Once upon a time, I created a tribal "emperor" deck using some slow-to-get-online-but-fun-to-play zombies. Banking on being the emperor and getting my engine(s) online before my guards die.
Now that they created both Anointed Procession and Wayward Servant, I had to remake the deck. Fun in it's own right, hilarious in emperor, this has become my zombie deck of choice. I love watching this thing work.
Well, one of the reasons I love this deck is all the little combo's that build into each other.
Like Zombie Infestation and Gravecrawler, discarding the little zombie to make zombies at instant speed, only to play him from the graveyard anyways.
Or speaking of Gravecrawler, try sacrificing him to the Corpse Harvester to create card advantage. Over and over again. For extra fun, fetch Korlash and watch your mana go BOOM, (while thinning your deck!)
Seriously, Gravecrawler, Corpse Harvester and Korlash are a serious engine and win condition. For two mana you fetch three swamps and a Korlash. Two mana for four cards out of your deck, while giving your Big Nasty Regenerator" +3/+3 permanently. It's very satisfying to play.
If you already got all the mana you need, feed the extra lands to zombie infestation.
And then there's Gravecrawler and Culling the Weak. Neat.
Anointed Procession makes Zombie Infestation a card for card trade, rather than a two for one. Or it's two for four, if you have enough Anointed Procession's.
But enough of the cutesie-wootsie card interactions, time to get into the really fun stuff!!
Endless Ranks of the Dead, is fun and flavorful in it's own right. Two become three, three becomes four, four becomes six, six becomes nine.
Add in one, just one, Anointed Procession and now your literally doubling the number of Zombies you have, every turn! 2 becomes 4, becomes 8, becomes 16, becomes 32.
To make things really cool, we'll add some zombies that have "when zombies enter the battlefield under you control get x effect"
Like Noxious Goul. If you got one Noxious Goul and one token in play, with ERotD and AP in play, all non-zombies get -2/-2, then -4/-4, and so on and so on.
Now what if you were using wayward servant? First would be 2 life, then 4 life, then 8 life.
And this compounding combo works if its two waywards and an ERotD, wayward servent and two erotd, etc, etc. I just love watching how fast things escalate in this deck.
It's really crazy if you get both ERotD and AP in play.
Let's walk through it real quick.
Anointed Procession acts like a substitution, and yes they do stack on top of them selves. At least, that's the way Magic: Duels plays it.
So let's start with two zombies, and the first ERotD. By itself, ERotD will give you 1 zombie token. The first AP will turn that token into 2, and the second will turn it into 4.
Now you got 6 zombies in play.
The second ERotD now will try to put 3 zombies into play, which one AP will turn into 6, and the second AP will turn into 12.
You just went from 2 zombies to 20. Hot. Dog.
What if the two zombies you started with were a Wayward Servent and a Noxious Goul? -18 life/+18 life and -18/-18 to all non-zombies.
