Why is Whip of Erebos not played?

Title pretty much says it all, but it seems odd that such a strong card sees no play? Reanimation aside, static lifelink seems great for creature decks that can afford the double black. Is it the lack of impactful targets? Or perhaps the quality of the graveyard hate is too good?

Thoughts?

Edit: thanks for the replies. I guess my nostalgia glasses for Theros standard got in the way.
