Strategy
This deck is how I went from 10 to 45 wins with an 80% win rate. It's Anti-Meta and beginner friendly. Anti-Meta, because it hits hard and fast and doesn't allow players to set up properly. Honestly, I think the deck is so unique players just have a hard time figuring out what to do. It's beginner friendly because there are no EX or high value cards needed. I didn't even realize this until I was making this guide.
I really like this deck. The main goal is to use your Bisharps as quick as possible. 30 + 70 dmg is a nice one, two punch. The deck's main advantage is swapping things out. The 2 Sabrina's, 2 X-Speed's and the Pidgeot means no one is safe. Players cant help but play cards. Punish them for it. In a Mewtwo Deck swap out Mewtwo for their Kirlia or Gardevoir. Continue just damaging monsters and rotating them.
