I feel like Image is going to rotate because I feel like the Illusion theme is going to rotate. Image wasn't really that unintended an answer to Legendary creatures, and having that answer available is highly relevant (Sigarda). They will for sure reprint Clone if they don't reprint Phantasmal Image. I wouldn't bet on Image returning, though. It had its time.

It's possible Reaper will return. I would like it, personally, as Reaper is a cool card and I think it's a pretty fitting Zombie lord. They don't always give lords to every color though (I believe there isn't a White lord in M12), so we'll never know.
