This is a game I was taught by some friends in Sweden, they called it Kabul, but I think it might have another name as Googling for it returned no similar results. I decided to write down the rules as it's actually a pretty great game!
EDIT: It was originally called Cabo, backstory here: https://treyhunner.com/2015/06/cabo-card-game/
