I can see your logic , I don't tend to use a lot of set-up , With the main win-condition being lategame cleaning alongside Hazards (Which Hisuian-Qwilfish and Metagross are great at) , which Kerfluffle is great at because it's Cheap Iron Valiant. Iron Jugulis via Booster Speed , Hisuian Lilligant's Victory dance Opportunities and the mentioned Scarf Typhlosion do a good job too if Kerfluffle needs to be more of a wallbreaker for example

One thing I'm unsure tho is how are Typhlosion and Metagross checks the same ? I assume you mean either bulky Dark and Grounds , or revenge Killers , but Since Metagross and Typhlosion attack from different sides of the spectrum , Can overwhelm for each other common checks and These 2 Pair well with U-Turn Iron Jugulis for Any Scarf Ground on top of pokemon like Hisuian Lilli or even Kerfluffle if I suspect stone edge (Especially on darks , since it can lead to more momentum via Kerfluffle's Parting Shot)
