I haven't seen anyone mention how much price pressure there is on legacy staples because SCG needs to have stock to run the events. They can't have weekly tournaments and then shrug their shoulders and say 'sorry, we are sold out of all of these staples'

So the buy price goes up, sale price goes up, staples sell out, repeat.

I am confident that the SCG tournament series is THE reason for the legacy price bubble and if/when they discontinue support the bubble will go with it.
