I have four of these in a BW life gain deck, and four Tainted Sigil's, where every creature has the lifelink ability. Blood Tribute is the cream of the crop when combined with this card, just tap your Vampire Nighthawk when casting Blood Tribute for the instant win.

I run this card in my black and green elf deck. Its lethal when paired with Nissa Revane.

Sanguine Bond + Pain Magnification + Sangromancer + any discard card = 3 life for each card in there hand and a hand emptying combo.

i run a black white deck, based around stopping whatever my opponent is doing and bleeding them to death.
pillory of the sleepless
pacifism
arrest
oblivion ring
cards like that to slow them down, then things like agent of masks, blind hunter, and the aforementioned pillory to bleed them.
sanguine makes nearly every card in the deck so much better.
faith's fetters becomes an arrest on steroids, plus an 8 point life swing, for 4 CMC, and souls of the faultless means you lose double your attacker's power.
while it requires a bit more of a specific build than most cards, it is damn good.
4.5/4

This + Blood Tribute + Wound Reflection = sheer awesomeness.

@Nismo
Me too! This is a pet card of mine, I've tried it in multiple builds and the only one it's stayed in is Nissa's elf deck, while I'm also experimenting with 
Soul Sisters at the moment...Tokens galore!

I used this in a White-Black deck. Dropped Angel's Mercy. Awesome Results.

This thing plus Tainted Sigil and a lifelinker = owned.
Let's say you swing with your 6/6 flying lifelink Serra Ascendant (as if that card is not broken on its own):
Ascendant swings for 6. You gain 6 life, Tainted Bond kicks in, opponent loses 6 life (that's 12 lost already).
Rock the Tainted Sigil, you gain 12 life, Bond kicks in, opponent takes 12 damage.
Result: ouch.
