It's Rhyperior LV.X; there is no Rhy PrimeFrom what I hear, Mew Prime and Rhyperior Prime are doing good.
I'm assuming you are referring to Reverse Time Dialga, is that correct? There are a lot of Dialga cards out there and I want to make sure I'm thinking of the right one.A good Los Gatos list runs both Delcatty and Dialga.
