Lets try this again gulliver, I REFUSE TO LOSE TO SOMETHING WE HAVE AN ADVANTAGE OVER!
I want you to start of with a Rain Dance. If he is going to change the weather this round, wait for him to do so then Attract.
Follow up by quickly Toxicing him. If he if going to protect, start of part 1 of the sky attack instead.
Finish of by either finishing off the sky attack, or use Aerial Ace.
Rain Dance / Attract ~ Toxic / Sky attack I ~ Aerial Ace / Sky Attack II
Also, Oslo, how do ya ref stat boosts? Just so I know.
