Old Stickfingers
Playing Magic Arena on Android using a Samsung Galaxy Fold 5.
When attempting to play Historic Brawl, I encounter a network error with only one of my decks. This deck is very simple and only contains a few different cards. After seeing online that specific cards might be at fault, I removed each card to see if I could play. When Old Stickfingers is my commander, I end up with "Network Error Unable to join event. Please try again later" when I remove Old Stickfingers as my commander and replace him with anyone else, I am able to search for a game. If I replace any other card in my deck, while keeping Old Stickfingers as my commander, I get the above error.
Something is bugged with Old Stickfingers as a Commander and doesn't allow him to be played in historical brawl.
