It happened on the playground.
I didn’t collect the cards for the game, I just liked the artwork, and some of the stories were quite cool. So while I hung around with the players, I just watched on, occasionally trading with them.
But she must have looked over my shoulder while I was looking at my foil cards, because she rather forcefully insisted we fight off, with foil cards held as ransom.
I think some of the rules she quoted weren’t accurate, so as she walked off with my foils, I asked the other players about it.
I was ridiculed.
