Mmmmmm..... were you around for the Reward changeover from Unlimited to the current, CL Reward cards?
I remember seeing $250 O'Shannus and I sold a Crystal for $5
By the time we got to 1M printed CL Rewards cards.... I was buying O'Shannii for $20 and Crystalsmythes for $0.50
Of course, things have come up since then- sold a few O'Shannii for $60/ea recently and CL Reward Rares are getting up close to $1/ea.
But you should expect to see the same pattern repeat for the CL release- Day 1, excitement and FOMO and 'new toys'! Prices will be high and some will spike.
After a month- there will be ~2M packs of CL in circulation and prices for most of the cards will probably be around what the CL Reward cards are now- $1 for Rares, $0.25 for Commons.
After that.... there will ANOTHER million packs (one, entire Untamed printing) released every month up through, at least, the Riftwatchers Pre-Release, when they may dump the remaining 10M packs directly on the market.
BTW: what is 'current value' or 'Last Sold'? $10? $11? is that what you used? Because I know I just bought 4 packs for ~$10.50
