[Witcher]: I challenged a man to a game of Gwent and he used a gold, high level card with his own damn face on it. Whats the deal? Whos regulating this? Should I make a 20 power card with my face on it to guarantee future wins?

Sure, if you're famous. 

Go slay a dragon, kill a few Kings, seduce some sorcereces, have several ballads written about you, and maybe then people will accept a powerful card with your name and face on it. 

Until then you can only expect people to laugh as some unknown mook tries to claim the most dangerous folks in the world are their peer.
