The official TCG website has posted information about another new card to the 'Platinum' set. Click on the card to get a higher resolution.

Gyarados [G] (Platinum, 30/127), owned by Cyrus, has the ability to spread around a lot of damage. Its Wriggle attack requires you to flip a coin for each of your opponent's Pokémon, and it does 30 damage to each Pokémon when you flip heads. It's not guaranteed to succeed, but if your opponent has a full Bench, it's worth the risk to damage multiple Pokémon at once. Dwindling Wave can inflict a devastating 100 damage, but as its name suggests, the devastation is diminished if Gyarados [G] is injured. For each damage counter on Gyarados [G], the attack does 10 less damage. Dwindling Wave requires 4 Energy to execute, so considering the effect of this attack, you may want to power up Gyarados [G] on the Bench before making it your Active Pokémon.
