If this Pokémon has at least 1 extra Water Energy attached to it (in addition to this attack's cost), when your opponent's Active Pokémon is Knocked Out by damage from those attacks, take 1 more Prize card.

Cosmic Eclipse set binder is where a full Cosmic Eclipse set goes. This card fills one slot there. A generation binder holds one card of each species. Dialga, Palkia, and Arceus can fill a slot in Generation 4 binder (Sinnoh). Themed lists that include this exact card are Dialga, Palkia, and Giratina. I still need this card.
