Mashup of Corpse Hauler and Winter's Chill.

I sat on this for a while, before deciding I didn't need the X, and could mash "return creature card" with "destroy unless".

I chose sacrifice instead of destroy as the templating was slightly simpler. I think it's ok this has an advantage to compensate for the fact it often won't do anything. Or is "destroy" better just because it's more usual?

I'm not sure if it's annoying to have to choose both targets at once, when the second one only matters half the time. But I don't think there's any alternative template.

Ooh, nice. It's like Feast or Famine, but the opponent chooses one. If you've got a big scary thing in the graveyard then this is really, really efficient removal, but that's a hard setup to achieve; in most limited games it'll only happen late in the game anyway.

Um... except you really want this to say "Target creature an opponent controls". Going "Hmm, you know, I choose not to sacrifice my Putrid Imp, so I think I get Emrakul instead" doesn't look right.

Thank you!

Oops, yes, will fix.
