Is this card broken?
Kind of
It's not , with the new rotation you don't have dimension valley , and damage change is 3 energy cost. This meta is fast as fuck. You can easily get 1HKO by mega fug

Nobody runs this Mewtwo with Dimensional Valley. The card is only good when used as a base for M Mewtwo Y and Shrine of Memories. Most decks can't reach 210 for a knockout on M Mewtwo, which makes Damage Change actually good.

Yep, All the meta cards broken as shit. Pokemon is going the way of Yugioh.
