Bring the pain - Bulid your Regigigas / Rayquaza with Manaphy or using colorless walls
Technical aspects of the deck "Bring the pain"
This deck Is all about building energy on to Regigigas or Rayquaza. There´s two ways to achieve this: either manaphy helps you charge energy, or by putting a colorless wall that can buy you time and heal them with Ilima.
The giant cape in Regigigas is key to withstand 150 attacks and revange with up to 200 attacks. I would recommend using the poison barbs as a bait for your opponent to use their Guzma, and at the end using the giant cape for Regigigas or Rayquaza.
The poison barbs also helps to chip the opponents pokemon. You can switch the Palkia origin form for an Articuno, I just felt this deck needed an extra energy receiver for the Manaphy because I was missing that extra pokemon to take advantage of Dawn. The Dawn is great to transfer the energy created by Manaphy or the energy you put on other pokemon while you were waiting for your heavy hitters.
