Mewtwo was in bad shape, but he'd pulled wins from worse situations than this in the past. He quickly leapt back towards the stage, but before he could get close to the edge, Twilight dropped her Study for just a moment to fire another Magic Spark at Mewtwo which knocked him further away from the stage. Twilight then returned to her Study, which was almost completely charged. As for Mewtwo, he might have used his jump, but he still had Teleport, which he used to get just barely on the edge of the stage. He grabbed onto the edge and quickly flipped himself back onto the stage, but when he got back on, he was met with Twilight aiming her horn at him once more.
