I ended up maindecking all the non-creature cards there. Went heavy on the wrath plan, and cut all the creatures below 4CMC. Certainly in Pack 1 the draft was looking like a steaming pile, but technically I was open to all five colors.
Either way, it's not a deck, to answer the OP. I think this type of thing can be a component of a deck, with Leechridden Swamp being interesting because of fetchability, but, it's pretty inefficient as far as closing power goes.
I think Dom was looking for Pod shenanigans in the draft. Specifically, a Delve card -> pod it into a 9 or 10 drop. Do we want these plays, and if so, which cards would work as pod targets (that would also see play elsewhere)?
Ruinblaster is probably more powerful, but Avalanche Riders has more interactions. Because I put such an emphasis on sacrifice effects, Riders is the more natural fit for my current list, but I ran Ruinblaster back in the day.
