Vermilion City Gym [Leaders' Stadium]

Whenever a player attacks with a Pokmon with Lt. Surge in its name, he or she may flip a coin. If heads, and if that Pokmon's attack does damage to the Defending Pokmon <em>(after applying Weakness and Resistance)</em>, that attack does 10 more damage to the Defending Pokmon. If tails, the attacking Pokmon does 10 damage to itself in addition to whatever its attack usually does.
