Actually, everyone knows that when you're mounted, the best technique is kaiten nage . . . . followed by eye gouges, hair pulling and a groin stomp. Once you get back to your feet, quickly sprinkle glass and lava on the ground and then you will have nothing to fear from a groundfighter . . .
We all know that in real life, then best method is to gradually scoot your opponent against some cage that you happen to be fighting in, then run out the time on the clock. After the time runs out on the magical clock you get a break and you will be rested. Then just resume the fight standing up.
