"Best defensive typing in Pokémon?"

Little bit of explanation and statistics for each. Note: I'm not including type combinations that currently don't exist like Normal/Ghost or Fire/GrassSteel/Fairy: 2 weaknesses and 11 resistances/immunitiesA great type combination which happen to cancel out most of each others weaknesses. Some notable Pokémon are Mega Mawile, Zacian-C, and Magearna. They're all good offensively AND defensively thanks to this typing.Dark/Poison: Only 1 weakness and 5 resistances/immunitiesThe secondary dark typing turned Muk from pretty bad to a great special wall when it got its Alolan form.Steel/Bug: Only 1 weakness and 9 resistances/immunitiesBug isn't a good type on its own but with steel canceling out 2/3 of its weaknesses it becomes quite good. Some very notable defensive Pokémon are Mega Scizor and FortressSteel/Grass: 2 weaknesses and 10 resistances/immunitiesAh the infamous Ferrothorn. It was pretty much mandatory on every competitive gen 5 singles team because it had an astounding 12 resistances at the time as well as an immunity to sandstorm and toxic. Also, Leech Seed is a notable move that Ferrothorn gets.Steel/Flying: 2 weaknesses and 10 resistances/immunitiesThis type is notorious for having some great defensive Pokémon throughout the generations. Nobody enjoyed facing Skarmory, Celesteela, and Corviknight. Basically, every single Pokémon that has this type combination is good.Dark/Ghost: Only 1 weakness and 4 resistances/immunitiesThrowback to when you were 9 years old and couldn't figure out how to hit Cynthia's Spiritomb super effectively. Even through fairy types now exist, it's still considered a good type. Too bad the only viable Pokémon with this type is Mega Sableye. This is slightly overrated if you ask me because, statistically, it doesn't stack up with the rest.​I would have loved to include more but I'm only limited to 6. Some other notable type combinations are Steel/Fire, Water/Ground, Water/Dragon, Ground/Flying, Ghost/Steel, and Steel/Dragon. I think there are enough types left over to warrant a part two so maybe I'll do that if this does wellView Poll via /r/pokemon https://ift.tt/3Csnp4r
