Energy absolutely needs to change

Just played two games of greninja weezing back to back where I went 6 waters in a row then 4 in a row on the second game (where I lost to a jolteon flipping 7/8 heads two turns in a row :^) thanks game) this nonsense absolutely needs to be changed. I shouldn't be punished this hard just for wanting to play dual energy in a deck where both pokemon only need 1 of their respective element
