Latest posts featuring Mega Diancie ex
Original creator of mega Diance deck. Currently Top 500 with it. 64% win rate last season. You can play PCL or Cyrus instead of sabrina, but I found sabrina to be most consistent. I recommend 2 giratina since getting early for energy generation is crucial. I provide extensive detail on how to play most match ups in the origianl reddit post in the original reddit post.
Espeon ex & M Diancie Endure your opponent's attacks with Espeon ex & Sylveon, all whilst charging up M Diancie and Giratina ex. When set up, inflict pressure with Espeon ex before dealing the final blow with M Diancie. Note that the stategy can change according to the board state & matchup.(edited)
