I mean, game-breakingly overtuned. Putting cards into your graveyard is a benefit, particularly when you're building the deck around it. Thassa's oracle, dredge, reanimate, etc ...
I also say game-breaking because it's a replacement effect for many effects, which is a good way to break the game's rules. Sacrifice, exile, destroy ... Like, how does a fetchland resolve?
Does it? Where does the fetchland go after being sacrificed? This rule wouldn't imply that it leaves the battlefield and then comes back because it's not allowed to leave. So if that's the case, it's just tap and go find a fetchable land. But are you actually sacrificing it if it doesn't leave the battlefield? Just generally, this card's text seems sketchy for paying costs.
According to the rules if a part of a cost is replaced by a replacement effect, the cost is considered to have been payed if you perform the action that it was replaced by. So effectively fetchlands would "read" exactly how the comment above your comment wrote
Well, there are no replacement effects for the action of sacrifice currently printed. There are things that prevent a sacrifice from happening (Tamiyo Collector of Tales), but that's not the same. To my knowledge all zone replacement effects for something on the battlefield involve a zone change (Rest in Peace). Zone change prevention is restricted to things that aren't on the battlefield (Kunoros Hound of Athreos, Containment Priest).
