After learning that a Sunny Day Moltres using Fire Blast has the highest special attack in the game it got me to thinking on how i could utilise this effectively. As a result i came up with this move set:-Moltres @ mysteryberry/leftovers
Substitute
Sunny Day
Fire Blast
Roar
I was always a subtle admirer of Moltres in RBY but never really saw its potential in GSC. This moveset has proved to be successful on many occasions. Any ideas or insight you could give me would be much appreciated. Cheers.

I may not be the knowledge on all things Pokemon, but I can sure as hell catch good ones!
