I'm unsure about Araquinid, I've used it in the past and its really underwhelming but some people have used it incredibly well. I do think Metagross makes opponents struggle in prep because of its access to both rocks and knock off as well as physical and special sets (versatility). Really unsure about talonflame and raichu though, you definitely do need a ground resist if you are tera'ing hydrapple.
