I thought of an interesting challenge

Basically take every Pokémon card you own out, close your eyes and pick 6 random cards. Depending on the cards you get you’ll have to use those Pokémon in whatever game they’re available in, you can not change your team whatsoever. You will have to try to beat whatever game you’re playing with that team only. You can make up your own rules as you go along, you just can’t change your team (and no legendary Pokémon.)
