I started off trying to make an updated Egon stompy deck, and it turned into zombie tribal. Can go tall or wide. I tried to keep it budget(≈$100) so I went with mono black and basic lands. Any recomendations are welcomed, budget as well as paths to fully optimized.
One Drops
Carrion Feeder - Sac outlet and helps get a draw engine going with Gravecrawler and Auger of the Undead.
Champion of the Perished - Can help the deck go tall with Carrion Feeder and Gravecrawler
Gravecrawler - The decks main engine. Works perfect as fodder for all the decks sac outlets.
Shambling Ghast - Here for a little ramp and can provide infinite sac fodder with Liliana.
Eaten Alive - I like this card as removal. While it's not an instant like Fatal Push, it works as another sac outlet and it hits any creature or planeswalker.
Two Drops
Jadar, Ghoulcaller of Nephalia - This could be Relentless Dead but 1)That card is pricy and 2) the consistent token generation helps proc Champion of the perished more.
Undead Butler - Another card I really like. It can help search for any of the good one drops and add them back when it's sac'ed.
Undead Augur - Draw enginge.
Three Drops
Rotting Regisaur/Demonic Embrace - The only thing left from the Egon stompy deck. Both provide a sizable threat, and Demonic Embrace works good with Undead butler as well.
Fell Stinger - Another sac outlet and can help draw up to three cards with Undead Augur. Also, deathtouch is nice.
Four Drop
Liliana, Untouched by Death - A good mana sink the provides lifegain, removal, and can help close out a game but swarming all the one drops with her ultimate.
