How it plays out: Press up and down arrows to dodge attacks. When the opponent to distracted/caught off guard (maybe you could use some sort of item to make this quicker?) you can attack. If they are not caught off guard and you attack, then they can block/dodge your attack.
I thought of this cool idea just now, hope it helps! Also sorry if you were going for an Undertale/Deltarune like gameplay style, I just thought that if you did that then people would call this an Undertale AU
