Hey Everyone, this is my first Smogon post and I felt tempted to make a tier list on the ZA OU Metagame based on my perception of the tier.
I have peaked ladder a bunch of Times with different teams and feel like I understand how good most Pokémon are, including the new megas.
The criteria for this list was that I would ONLY rank Pokémon i've seen or used. I tried ranking every Pokémon in an unbiased way regardless of if I use it a lot or not.
I Will talk a little bit about every Pokémon but I Will dedicate more time to Pokémon I feel like Hot takes.
Finally, Megas are ranked with different criteria from regular Pokémon, considering the opportunity cost of the mega slot, thats why you Will see a few megas below their base form.
Let's begin:
E tier are essentially all Pokemon I've always won against and never used.
In D tier there are some Pokémon i've faced or even used but had no sucess with or beat most of the time and they dont fill their roles consistently. Honorable mention to Mega Manectric which used to be really good before hidden Power ban but gets walled by every ground type now.
In C tier you can find Pokémon you Will see spontaneously, but not extremely Rarely, maybe 1 in 5 games for regular Pokémon and 1 in 20 games for the megas. Both Mega Zards are dissapointing in this generation, One is outclassed by Mega Pyroar and the other struggles to sweep in a tier filled with priority.
Although I do see Mega Chesnaught a lot I dont think it is very good and usually Win against it. Mega Audino is surprisingly annoying for some teams, Mega drill is very rare because usually sand can Run other megas + base drill, both Scolipedes are really good, they just struggle INTO Brave bird skarmory.
Mega Skarmory is scary some games with Weak armor set up + swords dance, but usually it thrives off surprise factor and doesnt work well in high ladder.
One thing I like a lot in this tier is how many Eeveelutions are viable. Both Umbreon and sylveon compete for a sloth on Stall/fat, with sylveon occasionally running specs. Vaporeon is good INTO greninja and non taunt volcanion tho it is a bit passive, Espeon shuts down most spikers like Skarmory and non Knock off Chesnaught while being a decent sweeper with cm and Jolteon is very good with choice scarf even after hidden Power ban imo.
Finally Blastoise is a decent bulky spinner pivot with flip Turn.
Moving on to B tier, your opponent Will usually have One of these most games, personally I like scarf Gardevoir, trace and healing wish are really helpful, Alakazam is a sand Staple and can Run both Lorb and Sash. Slowking is an underrated pivot that can sometimes match Better than slowking galar INTO volcanion and greninja.
A few of the megas here are disappointments compared to their base forms, especially dragonite and Scizor.
Aerodactyl is the main rocks lead, Meowstic is the main screens and spikes lead, while Slurpuff is the main sticky web lead. ( I forgot Slurpuff but hes B tier).
Krokodile is both a decent lead, amazing scarfer with Moxie and great alternative to Tyranitar on Stall as a pursuiter.
Mega Gallade is stupid strong and Mega Falinks is a decent sweeper.
Finally A tier, all the Pokémon here are amazing and Almost all teams have One.
Slowking Galar Almost made it to S tier, if not for the pursuit vulnerability, Aegislash I see a lot, it has many different sets and is very easy to fit on most offensive teams.
Hoopa and Volcanion have insane BST and are really powerful, versatile and bulky, The first can Run AV, Scarf, Specs, CB, Lorb, etc, and the second can Run Boots 4 Attack, Boots defog, Taunt Stallbreaker or Choice Specs.
Scizor and Dragonite are Staples on offense.
Zygarde always runs the Same set but is Braindead good.
Moving on to the megas, Malamar can be really scary with the right set. Superpower Knock Off Stored Power Rest is a crazy good set if your opponent doesnt have a dedicated counter.
Dragalge is a Staple on Sand and Fat, Walls Mega Gren and does wonders INTO Volcanion.
Mega Starmie is a crazy Mixed attacker, essentially has no counters if you have the right set and even its counters can be flip turned on.
Mega Sableye is a Staple on Stall and even balance teams Run it now that it has parting shot, its very underrated.
Mega Barbaracle, similarly to gallade is stupidly strong but it also has the option to Shell smash and sweep.
Mega Metagross has no counters and can break through everything if you spam t punch for long enough.
Mega Delphox also has no counters tho you need to have the right set. (Grass Knot vs Focus Blast)
Finally Mega Floette is probably the thing I hate facing the most, I feel like now that zygarde 50 is gone, it is the new Cancer in the meta and Will beat an unprepared team with sub cm protect.
Finally S tier, all teams in High Ladder have 2 or 3 of these Mons.
Starting with the defensive Pivots, Clefable and Slowbro are some of the best walls in the game.
The first can Run unaware, or Magic guard, wish port, hazards, cm, Knock off, T waves etc. These are glue for any non offensive team.
Skarmory is similar, tho it doesnt have a pivot move and is therefore found Mostly on bulkier teams unlike the other Two. It competes with Garchomp as the best spiker in the tier, tho it is definitively the best defogger.
Starmie and Excadrill are the only 2 really good rapid spinners. They both can be ran on pretty much any archetype, making them S tier easily.
The ONLY 2 megas I think are S tier are Mega Loppuny and Greninja, they are amazing speed Control and Revenge killers, tho they differ a bit on the teams they fit on.
Mega Loppuny is purely meant to be used as a Revenge killer. I dont think SD is good, the best set for me is CC, Return, Fake Out Mach Punch.
Greninja is more meant to be used as a slow progess maker tho it can also Revenge kill a lot of things.
It has insane movepool tho the most consistent set is flip Turn dark pulse water pulse water shuriken.
Base Greninja is the ONLY non mega, purely offensive Pokémon I think makes it to S tier, in part due to its versatility and unpredictability but also its reliability at doing solid damage.
Scarf, Life Orb Battle Bond, Specs, Nasty Plot Mixed, etc, with access to Gunk Shot and Low Kick it can break anything except Mega Dragalge.
Finally, I think Goodra H is S tier. It does amazing into most Greninja, Starmie Mega, Volcanion, Random Special attackers, while being powerful offensively, having Access to a very diverse movepool that can hit everything for super effective damage.
This was my tier list, I hope it wasnt very deranged from reality or biased in any way, I hope you find my opinion useful in your teambuilding.
