So after many years Pokemon has added the ability to take an extra turn something they really couldn't implement before until they added in these once per game mechanics. What helps makes something this powerful more balanced is that Dialga GX is a Dragon type and cannot hit anything in Standard for weakness. By how much Metal Support there is in this set it couldn't have been that type as with the Magnezone in this set they would have been too much.
I will miss Dragons having multiple different energy requirements but if they give them more powerful attacks and such since they can't hit weakness I will accept this for the better.
