I use it in both my standard and expanded M Manectric decks. I only play one copy of each, but with anti-EX decks such as Wailord mills and Garchomp floating around my league, it's always a welcome tech. It deals with Wailord stall in Standard and Wailord/Suicune in Expanded well, and Raikou with a Flash Energy helps against Garchomp in expanded, as Jirachi is the only other non-EX in the deck. I think this card has great potential, and similar to Wing Attack Charizard, will take a while to truly shine.
