Hi.(Not an english speaker, so excuse me)

I have a similar deck, althought I use Essence Harvest + Nantuko Husk (or Vampire Aristocrat, if you need the mana) instead of Gray Merchant of Asphodel or Gempalm Polluter.

I also use 4x Ghoulcaller's Chant and no Unearths, since the Ghoulcaller's Chant let me take 2 zombies for just one B, and since most of then just cost one or two manas, I can just put them in play on the same turn.

Don't know how to edit my post :(

Anyway, here's the list I use.

Any kind of help is welcome.

Hi Arantes90 (I'm not an english speaker too, so don't worry), thank you very much for your comment and your suggestions.

I thought of using something similar to Essence Harvest or Rite of Consumption as an ending, but i used the Gempalm (that makes you draw too! It's very useful!) and the gray merchant instead because they can be used more than once, whit some little combo as the one with the Chant, and also the Gempalm can't be countered when you use its ability.

About the Chants, i've left 2 Unearth because it can be cycled if not useful, and because in some situatons I would like to spare the 1 mana I would use to play a zombie from my hand, but i'll think about this suggestion.

Thank you once again, i'll check your deck.

I would run with 3xDisfigure and 3xTragic Slip. It seems that you could turn the Morbid trigger on more often than not and Tragic Slip handles the Ulamog's Crushers and Gurmag Anglers for only 1 mana. Also, I like Shamble Back instead of Vile Rebirth. Sorcery speed but it gains the 2 life that can be relevant in close matchups.

Hy HurricaneZach, thanks a lot for your suggestion and for your upvote. I think you are right about Disfigure and Tragic Slip, thanks for the suggestion. I also like Shamble Back, but I use this deck also against non-paupers, and in that case I find it more useful to have an istant istead of a sorcery (maybe with an opponent Graveborn deck or one like that). I will put it in the Maybeboard anyway, thanks once again!
