UPDATE: Roserade from Stormfront has also received an errata. Its Poke-Power, Hidden Poison, has the same error as Gengar – “Defending Pokemon” should now be read as “Attacking Pokemon.”
Gengar from Stormfront has received an errata that changes the wording of its Poke-Power, Fainting Spell. “Defending Pokemon” should now be read as “Attacking Pokemon” in the Power, since it was mislabeled on the printed English card. The new wording is below:
Once during your opponent’s turn, if Gengar would be Knocked Out by damage from an attack, you may flip a coin. If heads, the Attacking Pokemon is Knocked Out.
