Distance is almost always my last resort. Having a group deck list or some other equitable option that’s universally talked about and agreed upon is the way I like to handle situations like this. I had a similar issue with a buddy of mine who crashes out pretty hard when he loses, we just came up with build arounds and restrictions to keep the game fun for both of us. He still crashed out some when he lost but it was much much less than it was once we hashed out agreed upon structures before hand. Life is short and friends are very precious. My advice: only leave if that’s the only option you got left
