This is a fast paced Mega Sharpedo deck, that allows for you to ramp up a single Wild Swing Gyarados and also ramp a single Mega Gyarados. Once both are ready to go or close to ready, you can move into the Wild Swing Gyarados and discard the damaged Mega Sharpedo. Then when the 1 Prize Gyarados is taken out, you can move into the heavy hitter. (edited)
