Hahaha I just did what you did. Sorry for taking so long. My post is up.

I agree that the conditions should mix rather than replace. It frees up a pokemon to do something other than hail and sunny day turn after turn. I kinda described what I think the mix should be. The hail is not harmful to pokemon. It is just soft snow. The temperature does drop to allow the snow to stay. The sun light is diminished so it does not give as much of a bonus. All abilities triggered by hail or sunny day still activate. What do you say?
