Drivnod, Carnage Dominus does exactly that, and you can give it indestructible to protect your engine
The same is true for doubling the number of counters on a player
It all comes down to your personal needs and preferences
Because of the Adventure, you can really look at it as a potential 4-mana 2/2 that gets you a permanent back from your graveyard and that is also a card I would probably always play
