Pokémon Power: Bench Guard
As long as Brock's Rhydon is Benched, whenever 1 of your Benched Pokémon is damaged, you may do 10 of that damage to Brock's Rhydon instead. (If more than 1 of your Benched Pokémon is damaged at the same time, you may use this power once for each of them.)
Flip a coin. If tails, this attack does nothing.
