I remember struggling with Mewtwo a bit as a kid but I can honestly say I don't struggle against legendries to much.
I usually just have over 100 ultra balls use false swipe and then put the Pokemon to sleep and catch it. If it wakes up more than 3 times I usually just paralyze it I honestly never use more than 30 balls.
If false swipe can not hit the Pokemon I just use a move that gets it to red and then follow the original plan.
