I think it will definitely help with card values... but Chaos Legion prices are due to EXTREMELY high amounts of avail BCX with not enough "use"...

More players, more utility - Land, Soulkeep, etc... Card values will rise along with demand and Demand will rise across the board when there is a VALUE in the "junk" cards - right now a L10 Venari Heatsmith really isn't worth a whole lot and doesn't have much "use"...

I too hope Land and Soulkeep will cause the Demand and thus Price to rise... Supply is finite... and is Deflationary... I just hope we are right :)
