Some cards issued in country X may get added to country Y's Google Ads account & get threshold activated. And in this case if the Google Ads account goes live, it means your Google Ads account creation method is good, BUT, in the same very scenario, if the Google Ads account gets suspended (safe campaign), then it means that there is an issue with your Google Ads account creation method.
As a real example, I use certain cards issued in another country in US Google Ads accounts and campaigns go live (90% overall success).
If card gets accepted, main aspect is the Google Ads account creation method.
