In a E-Sports match and they banned or chose all my champions (i play support)

So when I was playing yesterday against another school they first chose Lux (my main) so i was like ok ima choose Sona, we lost that round, then next round I was like ok well I gotta play Sona again cuz they chose Lux again, then they ban Sona, I was thinking who am I going to play so I said I was going to play Ahri support my team was completely fine with it, next thing you know they ban Ahri, then my couch told me to play morgana, THEN THEY CHOSE FREAKING MORGANA, I had the worst of luck, then my couch came over to me and locked in Leona, I slayed as Leona, my very first time ever playing her and I learned her faster than any of my other champions I played, so we won the second match.
