Personally, I think choice scarf garchomp should be in other options. It is legit deadweight against so many teams right now, bulkier teams especially. Getting locked into either ground or dragon moves is terrible in this meta. Choice scarf garchomp is outclassed by almost every other scarfer, and a voice scarf gives up all of Garchomps breaking potential, which is its main niche at the moment. Yes, Scarf Garchomp can pivot and revenge kill volcarona, but so can Nihilego and Keldeo.
