Is Exquisite Blood useless without combo?

Hey guys, I‘m trying to optimizie my [[Clavileno, First of the blessed]] deck:

And I was thinking that [[Exquisite Blood]] doesn‘t really seve any purpose, since I‘m not running [[Vito]] nor [[Sanguine Bond]]. that‘s why I‘m asking if there‘s any other reason to play it?

Edit: I have decided to keep the card, as people convinced me it‘s still a good threat and value
