Yeah I expected the CP strategy to take a hit but nothing as severe as its been. I think its just a matter of time before it comes back though. Bots need to figure out how to rent and play the cards that allow them to win rewards. Once they do that, the CP grind will come roaring back as they all compete to get those silver chests.
As far as values going up when cards go out of print. I mean, they tend to do that because the liquid supply goes down since bots aren't winning them and sending them straight to the market but its still always going to come down to how useful the card is and how hard it is for people to get.
A card like Djinn Oshannus has 66k copies out there now and that will probably double before the run is over. That's a great card from bronze to champion and that's why there are only 345/66k on sale right now. That card has the ability to run back up to $10 or more after it goes out of print even with that many copies out there because no one is going to want to sell so the liquid supply will be low. But that was a $40 card early this year and people were saying then that it would go higher when it went out of print.
For most of these cards were are just too far away from the end of their print cycle to know what increasing in value looks like.
Hang in there. I think this is shaping up beautifully. Let's see how the market treats wild and modern. It sounds like they're talking to many gaming guilds who want to come in and just play modern. If that's true, we could see a large influx of players once that starts up who are only able to play with these new cards. That could add some renting pressure on CP and create more demand in these abundant new cards.
