Buy a Crystal Guardians' one, as soon as it's released. If you don't want to wait, buy LM's Shadowquake.
But as the Lunarock's part, if you can snipe as soon as possible, there's a chance off winning. See, Lunarock is a very tricky deck. Snipe with Reversals. But for the power part, I've just teched a Scizor ex and it's working real fine (well, this idea was originally made by , but I kinda stolen it). It just takes 1 bench space, nothing bad in a Lunarock deck. Most of the time I'll have Benched Solrocks and a free space for a Lunatone or a Scizor ex. Multi Energy'll do just fine on providing Scizor Metal Energy. I agree that Scizor ex may not be a great card, or even a good card, but can work REALLY good as it has speed and Lunarock is a speed deck.
