Blizzard know how to make an epic that is for sure. Great card.

Is the copied minion damaged? If so, this card has further synergy with Bloodsworn Mercenary. You can drop this, then Kargath Bladefist, then copy the damaged copy with Bloodsworn. 10 cost combo that would leave you with 12 rush attack (4/4/4), 3 copies of Kargath Prime in your deck, and a 4/3 and 2/2 body behind. Pretty good value! 

Same with Restless Mummy. This card, into Mummy, then copy the damaged mummy with Bloodsworn. 10 cost combo that leaves you with 18 rush damage (3/3/3/3/3/3) from the reborn mummies, plus the 4/3 and 2/2 bodies. Also very good!

Perfect card

Ho damn; this if a freaking amazing card. Health is often irrelevant on a rush minion, so this basically just acts like an Ixlid for them. I have a small rush package in my wild DMH warrior deck, and somehow finding room for this would give me:

* 3/1 Zilliax
* 4/1 Kargath, ultimately putting an extra Kargath Prime in my deck which I'll happily take. Probably never get a second Kargath Prime off this unless I have the coin.
* 3/1 Restless Mummy, complete with Reborn

I mean, Restless Mummy is just so good alongside this. Basically, for 7 mana and 2 cards you're dealing 3 damage to 4 enemy minions (or 3/6/9 with minions left over).

Keep in mind you can also Teron eat/resummon Kargath, as well as copy him with a Bloodsworn. In my Highlander Warrior deck, I could potentially shuffle four copies of Kargath Prime into my deck. Three of those copies would land consistently too (Teron is always vulnerable to a silence). 

Reborn synergy with that rush mummy= board clear
