It might be worth noting which stages can be scarred on.
The most popular ones are noted on the Essence of Wolf thread (Battlefield, Halberd, Yoshis Island (Brawl), Smashville, and Norfair) But there are a few, such as Pokemon Stadium 2, that aren't noted. There are probably more and it seems to be stages with an extended vertical edge, IE. stages without and edge like FD. I'll test the other stages out later when I get the chance and report back if you don't already have a list. Let me know if you need it I'd be happy to help out in any way.
