That's a bad strategy. Mewtwo will hit Laprad hard if they have Thunderbolt or will get a free shot at Jolteon.
Just open with Jolteon. Fire thunder wave and hope to get lucky with a few stuns then try to pin missile him down. That's his edge. He's 50/50 to land first hit, then 25% chance to prevent him from hitting every time.
