Weather control is lovely. Having a way to stop Snow Cloak or Sand Veil is really nice to have in Double Subway. The CPU isn't particularly consistant with whether they feel like switching out after bring Tricked a Choice item, or not. Which is something I found out when using my Scarfkiss+Garchomp team. Sometimes they switch immediately, other times they deactivate then switch. And of course sometimes they don't really switch at all.
