This card is just insane value. The fact that you can swing into an opponent creature and kill it without losing your own creatures will give you an insane board advantage, in most cases your opponent won’t be able to recover from that. Furthermore you can combine it with Execute which is basically the same as playing a Piercing Javelin that summons a 4/3 body, of course you can also combine it with Spiteful Dremora. As if it wasn’t enough, this card also has prophecy, which can negate up to 4 damage during your opponents turn. I played with this card a lot lately and it won me a ton of games.
