well i just started using it and it actually is pretty great.

this is pretty much the pivot set and the calm mind set put together, and it actually works surprisingly well. you can switch in on a sawk or something like you ordinarily would for the pivot set and set up a calm mind and sweep, or pass it to a different special attacker to support the team. i used this with a special samurott and eelektross and i could pass it to them occasionally and it was really great. you could use either moonlight or signal beam, but most of the time i found myself wanting moonlight more so that i could keep the survivability and i could still act as an effective pivot. this set is also great for setting up on walls and such.
baton pass/calm mind might not seem like so much of a big change, but it really is :D
if you dont have signal beam it is best used wish something to kill dark types.
