I've been using MCB's debit card (gold plus) for over 2 weeks now, and I must say I have no issues. The card works without any issue on PlayStore, Steam, Origin, Microsoft Store, and pretty much everywhere Visa cards are accepted. The only issue is that the session activation only lasts 15 days, but it's free to activate unlike UBL, and some other banks. I must say I'm pretty satisfied. I've purchased over 30 games from Steam, and never faced any issue.
