Is this a better place to report plugin mistakes, since the bug forum is supposed to be for lackey?
Anyway, the image for Obsianus Golem is wrong (it shows up as a Mystic Compass).
"Draco" has Cost (1)(6) and ConvertedCost 7. This should be (16) in both cases. This is also wrong for Aladdin's Lamp, Darksteel Colossus, and Stratadon.
You need to tell me if you are using the medium or high version. Obsidianus Golem (all versions of it) worked for me. Is that working for you? Try deleting the image for it manually maybe? If it still doesn't work for you, let me know.
I believe that is all fixed.
