Weavile-GXマニューラGX

AbilityShadow Connection

As often as you like during your turn (before your attack), you may move a basic Darkness Energy from 1 of your Pokémon to another of your Pokémon.

Search your deck for any number of Basic Pokémon and put them onto your Bench. Then, shuffle your deck. (You can't use more than 1 GX attack in a game.)
