Let me run you through the scenario that I would have to go through to make the set.
Me: We want to return to Kamigawa.
The Powers That Be (TBTB): Was it originally a successful set?
Me: No, it actually was a low point for Magic.
TPTB: Was the world popular even though the sales were poor?
Me: No, it’s actually the world that tested the poorest since we’ve been market testing worlds.
TPTB: Do you have newer market research that contradicts this data?
Me: No, newer data shows among our worlds it’s still one of the least popular.
TPTB: Then why do we want to go back?
Me: Because of the popularity of Commander and some use of the plane in more recent stories, there is a small but very vocal group of our enfranchised players that would like a return.
TPTB: Are there other worlds that this same group is also excited about that sold and polled better?
Me: Yes, a whole bunch.
TPTB: So, why are you bringing this to me?
Me: It’s a popular request on my blog.
Me: No, that’s it.
TPTB: We’ll pass.
Let’s just say it’s a *hard* sell to get made.
