How about Nantuko Husk and other cards like him?

Free sac outlets like Nantuko Husk are really good but the cards already in are more powerful than nantuko husk.

yourfavouritesquid hit the nail on the head, wbomb35. It may be standard playable, but the gigantic cardpool allowed in edh allows for better selection.

Some suggestions from EDHrec.com:

Caged Sun, Decree of Pain, Phyrexian Arena, Ghoulcaller Gisa, Overseer of the Damned, Blood Artist, Diabolic Tutor, Diabolic Revelation, Yawgmoth's Will, Diabolic Intent, Necromantic Selection, Dictate of Erebos, Sudden Spoiling, Malicious Affliction, Nykthos, Shrine to Nyx, and Deserted Temple.

This is going to be parsed out into multiple comments.

Caged Sun is a 6 drop that gets removed right away. Plus I can't really reanimate it.

Decree of Pain needs to find a slot, again.

I had Phyrexian Arena in there, but decided to use Graveborn Muse so I can recur it.

Ghoulcaller Gisa needs to be built around to be good. Her lack of haste really hinderz her in a faster deck such as this.

Again in a faster deck like this, Overseer of the Damned doesn't offer enough utility for its lofty mana cost.

To be continued.

So, I'm horrible for not responding, but long story short, thanks, Trockenmatt. Maybe has been updated.
