Tar Creeper was played in control to save you some health like this one does but could also be played on an empty board to help ping slow health enemy creatures whereas this one can't and will be a dead weight except if a hand/board buff aggro deck shines.
Also the 2 attack (versus 3 for Tar Creeper) threatens far fewer minions.
I don't see this card really played right now.
