Shark Week

Mega Sharpedo ex and Toxtricity make a great combo, accelerating energy onto any of your Dark Pokemon with the cost of 20 damage (so like Gardevoir ex but for dark types). This means Sharpedo's Hungry Jaws attack can do 270 damage quickly! You are playing Mega Lucario ex,and it is up front with full health left. How can we do 340 HP of damage, claim our last 3 prizes AND the game in this one turn?
