well.. steemit is a great social media to meet people. One day, i was asking about the voting rules of a witness I met a boy who helped me a lot at that time, I have been a year known on the internet and he has been a wonderful person. Coincidentally, he always give me steemmonster's cards and when the game season started, he asked me about what deck i had, I told him and he suddenly gave me 15 cards for the levels and i was starting to have a better rank within the game.
This is one of the many examples I know, another is that after several meetings between steemians, we started making friends and today they even stay at home to sleep.
That's pretty awesome that he just gave you a bunch of cards without asking. I'm sure that helped you move up in rank, it is pretty competitive. I just saw a post yesterday that they released prizes for the rankings, so maybe you will win some more cards!
