Have you ever seen a Clefairy drop a 680 power attack on an opponent? I have.
The goal of this deck is to get all of my energy onto my Pokemon to increase attack power for Mewtwo EX or Clefairy.
I start by getting as many Xatu or Clefairy out as early as possible.
4 Clefairy and I can play up to 4 energy per turn. 3 from Clefairy's ability, 1 from my hand.
If I go the Xatu route it will be 2-4 of them with 1 Clefairy to evolve into Clefable EX. This route allows me to get a good amount of draw. While Clefable EX gives me the ability to switch Pokemon without any retreat costs.
The deck works really well as it is right now, but I am still refining it.
I am currently at 17 energy, but it seems like the sweet spot may be 20 energy. I have energy retrieval and a supporter to get energy back once a pokemon gets knocked out.
If you have any suggestions, please let me know.
