Dialga Lv.68 Pokemon Great Encounters Rare Card # 16
Need a Legendary Pokémon in a hurry? Dialga’s (Great Encounters, 16/106) Flash Cannon attack does 40 damage and has a nifty devolving effect if you're willing to bounce all of Dialga’s Energy cards back into your hand. If you choose to do so, you get to remove the highest Evolution stage on the Defending Pokémon and shuffle it back into the other player’s deck. If the Pokémon under the Evolution card has lower HP than the amount of counters that were on the previous Stage, then it gets Knocked Out!
