Giovanni's Machamp (G2 #6)

Pokemon Power • Fortitude

If Giovanni's Machamp would be Knocked Out by an opponent's attack, flip a coin. If heads, Giovanni's Machamp is not Knocked Out and its remaining HP become 10 instead. This power can't be used if Giovanni's Machamp is already Asleep, Confused, or Paralyzed.

Flip 4 coins. This attack does 30 damage times the number of heads.
