Lum Berry Golem completely murders Lead Double Powder Butterfree, and still gets rocks up As for it being easy to predict, it can make a big difference. For example, lead Golem vs. Butterfree. If you Bug Buzz, Golem gets rocks up or flat out KO's if. If you Sleep Powder, Sawsbuck can come out and get the boost. Not that simple to predict, especially since you do not know Golem's item. And no one uses Roost on Butterfree because it is way too frail.
