Underworld Breach

I am honestly very surprised this card has not been broken in Modern yet. It's an absurd engine in Pioneer and in Legacy. I guess ironically Faithless Looting and Mox Opal would have actually both gone into the Modern version of this deck? Still, I am quite surprised to not have seen a breakout shell yet.

I don't know if people have found enough single-turn payoffs for it yet. The only place I've seen it was in a Hollow One/Ox build. It seemed mediocre at best. If it's gonna be broken, it takes more forethought than I have.

Hmm... what kind of cost reducers out there might be useful for this besides Hollow One?

Or maybe things with special bonuses if cast from the graveyard that don't have inherent ability to do so, or have more expensive alternate costs for doing so?

Or maybe things that can sacrifice themselves in very powerful effects with relatively cheap casting costs and additional sacrifice costs that you'd want to more easily reoccur multiple times in a turn?
