Take a look at these snippets of zoomed-in card art from the Mirrodin block. Can you identify the card to which each belongs? Try checking in at the Magic Arcana boards thread to discuss your guesses!
If you need a resource for looking up some art, try the Mirrodin and Darksteel product pages. They contain links to sortable spoiler lists chock full of "autocard" links. Or load up Magic Online and use its card search abilities to find art.
Tune in to Magic Arcana tomorrow for the answers!
