What is the most niche interaction that has won or lost you a fight?

I just lost a knockout round as squeak vs Bonnie. I stuck a bomb that would have killed her but she supered out of cannon mode and since she is technically a different brawler I guess the sticky bomb didn’t follow her jump into the air like most brawlers but stayed on the ground where Clyde had been then she landed on me and killed me to win the round.
