National Dex AG team

[AsuraIV]

Hi I'm totally new to any kind of semi-competitive pokemon, and was wondering what changes i could make to this team to improve it

annihilape: good staller while also being able to get in some heavy damage on other types, leftovers to improve survivabilty, STAB for rage fist allows for making use of the stall, and a boosted terra drain fist can let me build back health. Taunt prevents annoying status moves like poison or para from being used, allowing him to more easily push through teams
Fluttermane: Core sweeper, used after Skeledirge sunny day for photosynthesis terra boosted Moonblast, which I have found is able to clear many pokemon in one hit. Choice specs give the moonbeam extra oomph to OHKO more mons. Since I don't have koraidon, fluttermane is reliant on Skeledirge for much of it's damage, but still pretty good
Skeledirge: First pokemon thrown out usually, able to tank any early entry hazards until Corviknight can deal with them. Earth power lets it super effective hit mons like Miraidon. overall though, mainly used to set up sunny weather for Fluttermane, and stall for revives if needed with good Def, as it can sometimes be easily killed by a strong quick attacker due to its slow speed.
Corviknight: Hazard Clearer with defog, breaking the rythm of setup teams, and stalling with roost, good to swap in for predictions against ground type moves, as well as being fairly slow so you can utilize u-turn for a switch unpunished on squisher mons like darmantian. I mainly do just use it the same as Skeledirge, as a staller.
Darmantian: Anti-Dragon hitter with Icicle Crash, allowing it to hit dragon types such as miraidon. Earthquake allows for extra type coverage with Steel and Fire types in the category, such as Primal Groudon and chi-yu. I don't have a particular purpose for the Tera ice typing, except for the boost for icicle crash if its ever needed.
Dracovish: Physical sweeper, I put a choice sash on it cause i noticed it being outsped by a few mons, might switch it to a choice band though. one weakness is how it gets weakened by the sun from Skeledirge, but thats usually not a problem. The Fishious Rend allows for shredding fire and ground types like Ho-OH and Tyranitar.

I'm afraid that the team is just unviable as a whole for NDAG, but in more detail:


Annihilape seems like a fun wallbreaker and everything, but the very extremist direction of the metagame (as to limit to only either hyper offense or stall-like structures with minimal in-between) means that in practice either it does not contribute against the "bulkier" structures (Tera'd Shedinja, Assist + Revival Blessing teams, Baton Pass teams) nor the offensive ones (trending wallbreakers like Miraidon, Calyrex-S, and most notably No Guard + Fissure Machamp).


With its lacking physical bulk making this deceptively easy to pressure by any viable form of priority, and inability to properly overwhelm special walls like Ho-Oh before being KOed back, its niche is limited to a Pokemon that can revenge kill non-Scarf Koraidon as long it doesn't use the Tera slot, which is rather specific and at that point it's often better to just use Choice Scarf Calyrex-S.


Besides manual weather being unviable outside Doubles formats as the amount of turns used to apply the weather then bring the weather abuser turn it very impractical and easy to exploit, as well as weather from Primal Groudon, Primal Kyogre, and Mega Rayquaza entirely invalidating such weather (Protosynthesis does not trigger in Desolate Land), Skeledirge is rather niche as it checks little of note, namely Zacian-C, Koraidon, and Extreme Killer Arceus, beyond that being almost trivial to overwhelm by most special wallbreakers.


This is not up to the power level of the metagame, basically this struggles finding foes it can even wall, with most of the metagame threatening to KO it as the tier is filled with box art legendaries, in fact this invites Mega Gengar to trap it with Shadow Tag then enable a setup opportunity to threaten the entire team with Encore + Nasty Plot.


Besides a choice lock into Superpower inviting Mega Gengar to threaten a sweep and that move not really hitting anything that Earthquake wouldn't (Flare Blitz is a better choice), this is a very niche Pokemon and the support granted around it isn't up to the level of the tier to enable it properly.


I'll just quote something from an article I made on a related topic:

Despite Tera Water Choice Band Fishious Rend in rain OHKOing foes such as Ferrothorn and Mega Salamence, Dracovish is unviable. Unlike many of its D-rank companions, Dracovish isn't there solely because it is outclassed by more consistent Dragon-types for the tier such as Eternatus and Rayquaza. Primal Groudon is the best Pokémon in the tier and is on the vast majority of teams, rendering Dracovish near unusable until it is removed. There are plenty of Pokémon that Primal Groudon forces out, so why is Dracovish unviable compared to the others?

Dracovish has significant problems that extend beyond Primal Groudon. It is easily walled by Zygarde, which often uses Tera Water. Additionally, even with a Choice Scarf, Dracovish is unable to outspeed Zacian-C and Deoxys-A, which can both OHKO it. It also has trouble with many Dragon-types such as Eternatus. Consequently, Dracovish is constantly struggling for both power and Speed. It runs into too many roadblocks in nearly any game to be worth using.

While the above is focused to ND Ubers, in NDAG its issues are worsened by the meta trends heavily hindering virtually any chance for it to do much in a match, thus often just being KOed in practice, especially given its inability to outspeed most of the offensive metagame even with a Choice Scarf. Additionally, Dragon Pulse is out of place in the set as it's a physical attacker (remember that special moves use the Special Attack stat), and by extension Ancient Power is also unwise to use as even if the secondary effect triggers it'll still do very little at all.

Beyond all of this, I don't have to explain that stacking multiple Ghost-types isn't ideal, that leaves the team quite vulnerable to Ghost breakers like Calyrex-S, M-Gengar, Marshadow, and also prone to Pursuit trapping from Tyranitar and Kingambit (which have a role in the tier as to try checking Calyrex-S).

While I normally would recommend checking the meta resources for NDAG so you may familiarize with the meta trends, ultimately the format is dead and has minimal support for the reasons outlined here. This could almost could pass for a ND UUbers team if it wasn't for Flutter Mane and Dracovish (they're both banned over there), so I would recommend checking ND Ubers or ND UUbers and familiarizing to whichever one appeals to you the most by trying out a sample team against other players.
