We also have a tradition where whoever loses has to do a dare like walk around in wet socks for example(but it can't go too far)

Whenever I play Pokemon card games I never actually use any of the fancy ass tournament rules like "oh grab a random card from the deck" or "if someone defeats your GX they take 2 prize cards"; Me and my friends just grab 6 random cards of ours, and then just do the math on how much damage is dealt, and then whoever wins wins, nothing else
