Aerodactylプテラ

Poké-PowerUnearth

Once during your turn (before your attack), you may search your deck for Helix Fossil, Dome Fossil, or Old Amber, show it to your opponent, and put it into your hand. Shuffle your deck afterward. This power can't be used if Aerodactyl is affected by a Special Condition.

Flip a coin. If heads, discard an Energy card attached to the Defending Pokémon.
