Hey guys! You know how Zapdos is so good in this current meta???? You know what would be more awesome than one Zapdos???? TWO ZAPDOS!!!!! (Zapdoes? Zapdoeses???) WOWZA!!!!
In case the cringe distracted you guys for what I was building up to, I'm throwing my support in the ring for Electric/Flying.
As Zapdos has shown us in this meta, Electric/Flying is an insanely good defensive typing that resists a key number of core threats in the metagame. Most notably is its combined immunity to Ground and resistance to Fighting, which allows it to stonewall the ever present Great Tusk, as well as handle other top threats of these typings like Equilibra, Arghonaut, and Zamazenta. Other key resistances include those to Steel, Flying, Grass, and Bug, allowing it to wall other key threats like Kingambit, Venomicon (two of the S-ranks!!!), Malaconda, and Miasmaw. On the offensive side, both Electric and Flying moves hit a good number of threats in the metagame for SE damage, with the former dealing with mons like Venomicon, Hisuian Samurott, and Toxapex while the latter handles mons like Sneasler, Iron Valiant, and Great Tusk. Since our STAB combo hits so many threats, we can easily run one-attack slots to allow for much utility as possible while still scaring potential threats out.
The other main benefit of Electric/Flying is that it has very few weaknesses. Specifically, it only has two: Rock and Ice. While a Stealth Rock weakness isn't the most ideal weakness to have, especially for a wall, when you take into account how many resistances, immunities, and neutralities we have, the Stealth Rock weakness is essentially what balances this typing out. Zapdos is still a premier defensive wall in both OU and CAP despite this Stealth Rock weakness, and in general, being weak to Stealth Rock does not mean that you can be a good wall - just look at Talonflame in UU, which has a quad weakness to Stealth Rock and still manages to be a fairly high-ranked utility wall.
And just to address the elephant in the room - Zapdos being so good in CAP doesn't mean that a CAP 33 with this typing will be outclassed by or be forced to compete with Zapdos. By the nature of our concept alone, we are guaranteed to have excellent defensive stats and an excellent Speed stat. Zapdos's stat spread is much more heavily geared towards Special Attack, and its bulk and speed are a lot different from what we will be aiming for with CAP 33 - 90/85/90 bulk and 100 Speed look solid on paper, but are sorely outclassed by other walls and speedsters in the tier. Even now, Zapdos is primarily used as an offensive pivot, as that is where its strengths lie best. We've already determined that we will be playing a much different role from Zapdos, so I fully believe that an Electric/Flying CAP 33 can not only coexist alongside Zapdos, but thrive in the metagame and act as a viable counterpick to Zapdos.
To finish this post off, a quick rundown of my thoughts on other types, because this is getting long
Types I like:
Water/Ground: Probably my second favorite type combination aside from Electric/Flying, and one I was heavily considering making a post on myself. The sheer endurance of viability for mons like Quagsire, Gastrodon, and Swampert show just how effective of a defensive juggernaut this typing truly is, and I think it'll work wonderfully on CAP 33.
Dragon/Fairy: This was a typing I was a HUGE fan of during the typing discussion for Hemogoblin's process, so I'm happy to see that it's made a return as a strong contender in this process. It's just such a solid typing all around with so many key resistances. The weaknesses to Poison, Steel, and Dragon do worry me, considering as all three of our current S-ranks have those types, but the positives far outweigh the negatives here.
Grass/Steel: The Ferrothorn copium is strong within us Jokes aside, this is just an extremely strong defensive typing all around, and for good reason. So many resistances, including a Stealth Rock resistance and an immunity to Toxic, make this a no-brainer choice for a wall.
Types I dislike:
Dark/Fairy: Ending things off on a bit of a hot take. This typing looks very cool on paper, and I was extremely excited about it myself! ...And then I took a look at the viability rankings, and I realized that wow, this type actually sucks balls into most of the big threats!!!! This would make us a Dark type that cannot reliably check Kingambit, Galarian Slowking, and Gholdengo due to our weaknesses to Poison and Steel, and we also match up horribly into many other top threats, like Hemogoblin, Equilibra, Iron Valiant, Iron Moth, and Heatran. I do realize that Dragon/Fairy also has similar problems, but it's balanced out by the Dragon typing helping to make up for these weaknesses - most notably sporting a Fire resistance to help with Hemogoblin, Iron Moth, and Heatran - and the lack of the Dark typing giving it more key resistances, particularly that Fighting resist. It does allow us to wall Dragapult, but that's basically the only thing it does. I'd love to have my mind changed on this, because it is a cool type, but as it stands now, I just think it falls flat. I've seen a lot of people supporting it due to how good the dual STABs are, which is certainly good and all, but I feel like Electric/Flying does a much better job of that while also matching up into the current meta a lot better.
thanks for coming to my TED talk guys hope you all have a good day :333
