Finals at the Tournament: Elemental magic vs Swap ability

" Once I'm finished with you I'll challenge the school council and take their positions", She's confident that she will win against me, she's definitely looking down on me. I jump out of the ring and used my swap ability before I hit the ground, we change places, " elemental magic, rock stairs!". She smiled at me and clearly this match is far from over. " elemental magic!, ice sword!,". She definitely knows about my ability for sure, I'm at disadvantage here. she run towards me and swing her sword, I was able to dodge her attack. I throw a rock into the air, " swap ability!, switch!". Bella is falling down mid air, " elemental magic!, ice: Slide!", She create a slide and she landed safely. what should I do?, I used my strongest ability, I can't use it again. " if you can see your opponent you can't switch places with them, that quite a weakness". what should I do?, even I switch places with Bella, she will counter it using her magic." what a troublesome you are", she smiled like she's enjoying that I'm struggling. " Elemental magic!, Tarnishing Tornado!", she use again her powerful magic, a giant tornado is in front of me and what should I do?. Am I gonna lose?, I have to beat her so I can avenge Haru, but how?.
