I just found out about a great combo, it is the Gym Leaders Rhydon and Fossil
Articuno. Articuno's Blizzard does 50 damage with the chance of doing 10
damage to either your or your opponent's benched pokemon and Gym Leaders
Rhydon has a pokemon power that if hes on the bench, whatever damage caused
by attacks to your benched pokemon is reduced by 10, if you get a tails,
nothing happens to your benched pokemon and Articuno just did 50 damage.
