Shooting teams aren't too great, especially because, right now, captains are very hard to come by; however, in the future, Shooting teams will become pretty powerful.
Curiel only gives a 2X ATK boost and 1.5X RCV boost. This is pretty bad. RCV isn't that important and getting only 1.5 makes it even crummier. But Zephyr isn't out yet, so Curiel is the best you'll get for now.
Zephyr gives a great boost to shooters and his special
makes their ATK even higher. He's going to be the only
one leading Shooting teams for a while.
