I was excited when the card Buried Ruin came out, unfortunately I've been putting the lion's share of my time into my recent exam and any time I've put towards magic development has been working on fixing some of the kinks in Dredge. This has been compounded by the fact that my friend recently lost his collection and his expertise lies in shops, so I had loaned him my Shops deck. Has anybody actually had the opportunity to stretch this card out and do any testing. According to Morphling.de it has yet to make a top 8 appearances. I thought it would quickly snatch up the spots traditionally held by Mishra's Factories or Ghost Quarters, but this seems to not be the case. I'd be curious to see some of the insights and results people have had from actual testing.
I, along with a few others, have done some work with the card. I tested some games against Paul at GenCon with a version of Espresso that ran Buried Ruin as a recursion engine.
It was a bit too slow, even for a grindy kind of game, for Espresso at least. The activation, at two, is problematic at times. If it was a tap, sack, or a pay one, tap/sack it would probably have broken into a top 8 by now. There might be a home for it in the future, but I wasn't very happy with it (though I thought I would be) and have since put it down.
I haven't even picked up foil ones!
