I think this is a bit extreme. Pack sales slowed down from the FLOOD of new stuff the team released at once... TOO MUCH TOO FAST. This seems like a very shortsighted way to address slow sales. Better timing of releases (ie SPACED OUT JUST A LITTLE) would have been a better move imo. Why not wait for land to be released and see how many cards get soaked up from that alone? This is jumping the gun. Plan ahead a little better with new release timing and you will see packs sales be more consistent. A lot of the community is tapped out from RW, TD, GLX RUNI etc. Give people some time to recover and pack sales will pick up!
I also like Dave's idea of replacing the LB prized with packs... kills two birds with one stone!
You guys need to stick to your mantra: LET MARKETS MARKET!!
