It helps if you are a music lover (like me). I don't know what it is, but this game has something and keeps pulling me back. The fact that some cards are already OOP (Sid and Skater), creates that demand.

People want what they can't get, and may be willing to pay for it.

Congrats on your two 'Sids!', I pulled the last one while writing this and used my pull in the post as an example. I will be keeping an eye on the market-stream to see if anyone is willing to buy these at some inflated price.

There were a couple of Lead Guitarists for sale yesterday, I expect them to disappear soon. The Mods (one of the better people) have all been sold.
