The guys at Magic Traders added Magic 2010 to their pricelists last night, which means Black Lotus Project now has some data to work with. Tenth Edition cards that were reprinted in M10 were getting odd values because M10 wasn't in the pricelist yet. Birds of Paradise, Twincast, Pithing Needle, and a few other cards were taking credit for sales that didn't belong to them.
A particularly curious card was Drowned from The Dark, which looks like it was taking the volume and pricing data for Drowned Catacomb from M10. There's no simple way to correct the bad data over the past two to three weeks, but I don't think it should cause any problems in the long run.
Check out the new most popular cards chart, which is dominated by Magic 2010 and likely will be for several weeks.
