For PSing, deathball rocks. They are easy to stack, I overpowered a fully charged and turboed Kame with 3 deathballs one time...pwn. It is so big that any incoming beam will get caught in it. One time on riverside, I hurled a deathball at the other spawn, and started a PS with someone. One of his teammates charged a beam and helped him out, but the db was still winning. Then 2 more of thier team started helping and it starting coming toward me, but I was already charging another db and it was about full. I threw it, and the blast that resulted engulfed the whole map. Awesome. Frieza is awesome.
