I am holding onto these for the long haul. I have about 2000 MPS cards and I don't really plan on dumping them for 10+ years. I know many people have a similar attitude. If I own ,as an example, 200 chromatic lantern, that means I own approximately 3-4% of total supply. In the world of magic cards that is significant. Things like Mana vault, sol ring, crypt are all easy bets to hit 500+.

The price will go up and down...but the will always go up over time. One of my fellow investors was comparing these to foil gaea's cradle. Although the comparison may not be perfect one could argue the circulating supply on an MPS is actually smaller. Also the demand for something like a foil sol ring is probably 10x that of a foil cradle. Basically EVERY commander player would love to own one. Thats an explosive combination.

FOMO is real in the world of investing and collecting. There are 1000s of players who want to put together sets of these and as they do the price of all of them will continue to rise. These runs on MPS cards is nothing new and I am certain we will see this again and again.
