Cruel Bitch

Bring out your dead! Fill your graveyard as fast as you can, by any means you can, bring back any creature that is able to come back, fill your opponents graveyards as fast as you can as well. This deck has several viable big hitters that can end the game in a hurry. 1) If Phage hits the field with Lightning Greaves & Whispersilk Cloak...game over. 2) With fast filling graveyards, Avatar of Woe will be on the field in a hurry. 3) If Liliana Vess comes onto the field late, with a big full graveyard, it won't be long until she puts them all back into play. 4) Liliana of the Dark Realms is all about swamps, if you have plenty in play, the game is almost over. 5) Rotting Rats, Nether Shadows, Necrosavant, Undead Gladiator all bring themselves back from the dead. 6) A big graveyard makes Revenant a fast game ender. Most of the rest of the cards either benefit from a big graveyard, or are used as fodder to fill said graveyard as sacrificial offerings (or spells that force sacrifices/discards).

This deck isn't about defense, it's about pushing it's own agenda. Most of the fodder are worthless as attackers and are equally weak on defense. Keep mana potential in your head at all times...those Thrulls are in this deck to generate mana and feed your graveyard, be sure to utilize BOTH of them, only waste them on defense if it's done to stop a really, really big threat that doesn't have trample.

Bide your time until any of the mentioned game ending threats can be brought to bare.

I may need to add some Diabolic Tutors or similar cards, just to increase the likelihood of getting cards in hand that are really needed. More play testing is needed.

The deck is 50% creatures, and most of them only cost 1 mana or 2 mana. This deck is very playable even if you only start with one land in your opening hand (though 2 would be better). It's not a deck that needs a lot of land to be effective.
