Hello, I'll bump this with two teams we used in the RU Snake Draft. They were built prior to the introduction of Rhyperior and Seismitoad but I believe they should be OK against both of them.
The basic idea of this team is to wallbreak with Life Orb Starmie. Incineroar is a great partner, Knocking off Water-types to make them more vulnerable to Starmie and bringing it in against defensive Pokemon like Rhyperior and non-Scarf Flygon. Dhelmise Rapid Spins so that Starmie doesn't take too much recoil while also making up for its inability to check Flygon, Rhyperior, and other things you want your Water-type to answer. Nasty Plot Togekiss adds another great special breaker that works well alongside Starmie, and it appreciates Dhelmise and Scarf Flygon's ability to check Electric-types. Registeel rounds out the team, soft-checking most of the tier and threatening Togekiss with Heavy Slam.
The basic idea of this team is to spread paralysis for Chandelure and Togekiss while also threatening to win with Snorlax, who also provides plenty of defensive utility against threats such as Volcanion and special Necrozma. Chandelure is Scarfed in order to better check Cobalion for Snorlax, who lets it in fairly freely. I initially had Hex to take advantage of paralysis and more strongly threaten DemonGross, but Energy Ball may now be more useful for Rhyperior and Seismitoad. Dhelmise spins for it, and Coba and Togekiss answer Dark-types well (with Heal Bell Togekiss making Snorlax's Rest less inconvenient). Scarf Flygon is on the team to serve as a great cleaner as usual.
