Funny you say that I was playing against my testing groups megaray list (megaray with milotic) and we thought that was a less than terrible idea but delinquent probably stronger.
How the matches went where I got to chaos wheel my stadium in: he would try to burn burn then hex for knockout. (running 3 dragon 1 normal ray) but I would retreat into another tina after the second burn and N again. Was really brutal. He was able to easily win games but if I hit 2 elixirs onto tina and chaos wheeled the stadium in the match was all but over.
