As you, I am also a member of 2K22 MT. I also spent a significant amount of 2K22 MT playing the game. Since there are so many limited edition sneakers, jerseys, player cards and so forth. I'm not able to resist buying.
For the player card, I think what I'd like more than anything else is Pink Diamond cards. It is important to know how costly this can be. However, for the gaming experience, I am willing to pay.
I would recommend a trustworthy seller. NBA2king.com provides support 24 hours a day and their prices are affordable. If you are looking to purchase 2K22 MT, go through the site.
