LOL, I just tested the Palkia and Dialga Legend/Shaymin EX deck, it's terrible, the PDL dies too quickly, setting me back 2 prizes, Shaymin is hard not to be killed and the deck is so slow with no energy acceleration. and you need a ton of energy 2 metal per Time Control. So to make them take 6 prizes you need at least 12 metal energy (and the ones that are used for the colourless.) In short, like you told me it's terra-bad.
