I want to use a team where my Rotom-Frost uses snatch on my Kommo-o while it uses Clangorous Soul (balanced move btw) then send out my Abomasnow with Snow Warning so Rotom-Frost can spam Blizzard. Would it be able to snatch Clangorous Soul? I know you can't snatch Geomancy (imagine if you could), so can you snatch it?
Clangorous Soul does have the Snatch flag. That means Rotom will be the one losing its health, not Kommo-o, so keep that in mind when determining how fragile the setup is.
