>>54395338>Typhlosion's Fire/Ghost evo being reliant on Mount CoronetIt's explicitly spawning in the Crimson mirelands and the pokedex mentions it eating ghosts.
I think you need to raise a Thyplosion from a Cyndaquill while letting it prey on Ghastly & Yanma, letting it eat whatever tubers are availible in swampland (which isn't a popular spot for fire type trainers due to water and ground types) and practice mixing shadowball with will-o-wisp.
>DecuideyeRaise in a cold mountain climate and let it prey on Rhyhorn and Gligar (which rangers won't take kindly to).
>SammurottPreys on White Basculin, Rufflet and Bibarrel in icy rivers.
So you'd basically have to revive another species.
>White BasculinYou'd have to breed out the inbreeding out of regular Red and Blue basculin and somehow force the two subspecies to breed with each other.
>H-SneaselCould pop up as a warm weather mutation in the mountainside but normally don't get caught or are dismissed as a colour variation like shiny pokemon. Probably live in remote areas that even rangers don't patroll.
>UrsalunaUrsaring were driven from swampland and most of it was claimed by rice farmers who hate the bears.
Most other swamlland suffers from pollution and is either drying out or full of grimer.
>KleavorProbably needs an unreasonable ammount of Augurite which is moslty found in areas with rock and fire types (Hard enough did a good take on this).
>H-QuillfishProbably feed on Drifloon who only appear in colder climates.
>WrydeerProbably only the alpha of the herd and their strongest offspring learned the move so something must have happened to the herd the Wrydeer from PLA was part of.
