I do not get this "limited run" decision. If MM is only sold in the LGSs, and for a higher price, pretty much any MM card will be more expensive and have a lower print run than the original card, and with Magic already being expensive enough, MM can only steal from a player's Standard money pool.
I elaborate: if MM reprints Bob (Ravnica's Dark Confidant),
that reprint Bob will have a smaller print number than the original. And
this difference will be even larger for commons and uncommons, which in
their original printings, like Bob, were available at Walmart and
Target. (I wasn't around for that but I assume that Magic cards have
been available at Walmart and Target for many years).
If MM is
not available at Walmart and Target, and is not priced like the regular
packs-and both of the former are true; it has a high probability of
being a lesser failure than Commander's Arsenal, but not the thing that
will bring out the modern-playing zombies out of their graves.
