How it was given out: Pokémon Trading Card Game 2: The Invasion of Team GR! insert.
Japanese promo, released 2001.
One of 278 promos from 1999 to 2003 listed on this site.
Whenever 1 of your Pokémon with Dark in its name does damage to any Pokémon with an attack, flip a coin. If heads, flip another coin. If the second coin is heads, that attack does 20 more damage. If the second coin is tails, that attack does 10 more damage. If you have more than 1 Team GR's Mewtwo in play, use only 1 Dark Wave for an attack. This power stops working while Team GR's Mewtwo is Asleep, Confused, or Paralyzed.
Flip a number of coins equal to the number of Pokémon with Dark in their names on your Bench. This attack does 20 damage plus 20 damage times the number of heads.
