I am reading the Ability "Strong Charge" correctly on Vikavolt SUM52. "Once during your turn (before your attack), you may search your deck for a [G] Energy card and a [L] Energy card and attach them to your Pokémon in any way you like. Then, shuffle your deck." I interpret this as you have to pull both a Grass and a Lightning Energy and attach them any way you want. I have seen PTCGO and some streams from events where they were only pulling one or the other. Please post an official ruling on this. Thanks in advance.
