For anyone who's interested, we (mostly nyttyn and Snobalt) made a brief skeleton analysis for Naviathan back during Moveset Discussion. You can find the full post
here. While it was based off of speculation, you may be able to glean some ideas about why we designed CAP 20 the way we did. It should also help alleviate some questions about coverage / optimal spreads. If you have anything you'd like to add here for when we put it up on site, let us know by posting!
CAP20 Skeleton Analysis
- A dangerous set-up sweeper that, while not the top of its field in either category, can perform either a quick Dragon Dance sweep or a prolonged Calm Mind sweep.
- Water/Steel typing provides a plethora of setup opportunities, aided by both Water Veil and Heatproof
- Somewhat lackluster without the ability to setup
- Best on teams that can provide it the support it requires.
Dragon Dance + 3 Attacks
Name: Dragon Dance + 3 Attacks
Move 1: Dragon Dance
Move 2: Waterfall / Iron Head
Move 3: Iron Head / Icicle Crash / Ice Punch
Move 4: Wild Charge
Ability: Water Veil
EVs: 48 HP / 252 Atk / 208 Spe
OR 252 Atk / 4 Def / 252 Spe
Nature: Jolly
Item: Life Orb
- Because of CAP 20’s Steel/Water typing and Water Viel ability, it is able to set up Dragon Dances on a plethora of common mons, such as Clefable and Mega Sableye.
- Dragon Dance allows it to outspeed the most common Choice Scarf user in the tier, Landorus-T.
- Waterfall and Iron Head are your main forms of stab, allowing you to deal with bulky ground types as well as pesky fairies like Unaware Clefable who are 2HK0’d despite ignoring your boosts.
- Ice coverage gives this CAP perfect neutral coverage alongside Wild Charge and hits Landorus-T harder than Waterfall does
- Wild Charge rounds out CAP20's coverage, giving it neutral coverage on most of the metgame, barring a few exceptions such as Ferrothorn and Gastrodon. Wild Charge lets CAP20 OHKO Mega Charizard Y and Keldeo at +1, and heavily damages foes such as Mega Slowbro, Suicune, and Skarmory, allowing CAP20 to sweep past them if they have been sufficiently weakened. Keep in mind that Life Orb recoil piles up quickly alongside Wild Charge recoil.
- Partners that can provide entry hazards are greatly appreciated.
- Best used to clean up heavily weakened teams or teams full of frail members.
Calm Mind
Name: Calm Mind
Move 1: Calm Mind
Move 2: Scald
Move 3: Slack Off
Move 4: Flash Cannon / Refresh / Taunt
Ability: Heatproof
EVs: 252 HP / 252 Def / 4 SpA
OR 232 HP / 252 Def / 24 SpD
Nature: Bold
Item: Leftovers
- Calm Mind is required
- Scald is primary STAB move
- Slack Off heals off damage taken
- Last move is filler. Flash Cannon allows CAP to beat stuff such as Clefable and Altaria and Refresh allows it to heal off status, primarily paralysis and burn.
- EVs and item are self explanatory, while the second EV spread ensures Timid Heatran does not 2HKO with Earth Power when the CAP is at +1
- Scald allows CAP20 to still be useful before it sets up, by coming in and burning would-be switchins throughout the match.
- Best used to demolish defensive teams when checks/counters are either heavily weakened or taken out of the picture.
After reading this, these sets were supposed to be the defining and main sets of Naviathan, being able to function as 2 completely different sweepers, however, these sets/spreads really need some tweaking to really showcase what Naviathan is capable of doing. The last 2 bullets points actually made laugh. One of the best sets it has is no set which I have explained as to why that is and I don't see why need to tell people the obvious, like, I'm pretty sure that's common knowledge when building a team, but i dunno.
Starting with the DD set, I don't understand what that HP invest is for as it's never explained, just seems it is there to look cool tbh. Ice coverage is so bad on it as well, as it only hits 2 Pokemon, Lando-t and Garchomp. Waterfall 2HKOs Defensive Lando with a bit of prio damage and it OHKOs Scarf, and it just adds more counters to it, as it unable to hit anything with a Water typing, but if you are reall that desperate to beat it, by all means run Ice, but I'd rather use Return as it actually provides amazing neutral coverage with Water.
252 Atk Life Orb Naviathan Waterfall vs. 0 HP / 24 Def Landorus-T: 322-382 (100.9 - 119.7%) -- guaranteed OHKO
-1 252 Atk Life Orb Naviathan Waterfall vs. 252 HP / 240+ Def Landorus-T: 159-190 (41.6 - 49.7%) -- 28.5% chance to 2HKO after Stealth Rock and Leftovers recovery
And saying that Naviathan can set up on Mega Sableye is a bit iffy, not only is Mega Sableye not common in the OU metagame, Foul Play prevents Naviathan from setting up on it, despite in being immune to burns, it's gonna lose to Mega Sableye, unless you get really lucky with hax which isn't a valid option at all.
The CM set is the set that really shines, because the coverage it has works so much better on the special side, rather than the physical and the extra bulk you can invest makes it really durable. However, not invested, it's really slow and not hard to revenge at all, even after a CM it can be revenged meaning that speed is crucial for it to be really amazing, otherwise it seems like a waster to have such a good speed stat and just not use it. Substitute can be used over Slack Off, as boosting behind a sub with that bulk is terrifying and this what makes the slow boosting set a true force to be reckoned with, making revenge killing really hard and aids its setup even more than recovery can do for it. Flash Cannon isn't all that great on it either, as you beat Clef anyways and only DD Altaria is a threat, which has to risk being burnt by Scald to beat it, and even with Heal Bell/Refresh, Taunt just shuts this down completely and becomes setup fodder for it and should be the primary slot over Flash Cannon.
Speaking of which, Taunt is the move that really broke Naviathan and has allowed a no set-up option to be really good; A fast taunt user that is immune to Toxic and takes half damage from burns with recovery alongside an amazing defensive typing and bulk. Iirc, Taunt was so 'the Calm Mind set got something good as well as Dragon Dance' or something along those lines, but it's turned Naviathan into a fat stallbreaker than the double set-up sweeper we envisioned.
In short, DD has failed due to having no powerful STABs and need Life Orb to do anything, making revenging / whittling super easy and walled by a lot of mons where CM has outdone itself because Taunt is broken on it and should have never been allowed in the first place.
