Hi! This is an edit for my OU team post. More or less made to attempt to try to get back into OU, any advice helps, from move changes, item changes, Pokémon to change, or scrap all together. I'm just trying to get used to team building again. built somewhat around taking out cresselia counters allowing it to setup calm mind and sweep.
Zapdos - A good damage and pivot which can threaten Gholdengo and gambit with heat wave and bulky enough to suitably use roost and high enough speed to out speed Gholdengo and great tusk. found to be a decent damage mon with enough defense to survive and roost on mons that are burned or paralyzed. volt switch is just a good pivot tool unfortunately affected by the many ground types in the tier. Terra steel to allow it to terra on threats like galarian slowking and wall it somewhat.
Great Tusk - a good all around defense tank with rapid spin for stealth rock, spikes, etc. replaced CC with stone edge to hit defensive treats like moltres, I opted for this to be the only spinner just because most other mons are either resistant to rocks, have boots, or have levitate for spikes. between scarfed meowscarada, heatwave Zapdos, and Moltres, Gholdengo has a hard time switching or staying in, so it isnt the most important thing to have defog or rapid spin. Rapid spin can also be used as a decent speed increaser to allow for headlong rush to kill or maim other mons
Moltres - Good all rounder half defense half special threat that can status any physical walls with will-o-wisp and flame body. good pivot in uturn and recovery in roost. Max SpA for decent damage on non resists and devastating damage on super effective hits. U-turn to pivot out of mons that will swap to keep momentum up. Tera water for fire weaknesses and neutral damage attacks from mons like great tusk stone edge or Sisui Samarot razor shell. seems to be just a mon that has many opportunities to wall, damage, or gain momentum in the battle.
Walking wake - Good utility mon that can sub on toxics and setup moves. between decent defensive profile, mediocre/mediocre-low bulk, and leftovers, can swap I'm somewhat efficiently to medium power neutral attacks, and same high power resists. takes less that 25% from Garganacle salt cure so can sub directly in its face or on swap in and harass with hydrosteam or roar. found to be a half decent lead with sub and road against many mid ladder set up mons. and a good recipient of u-turn or volt switch from friendly mons.
Meowscarada - good utility and pivot with scarf to out speed many swift swimmers, shell smashers, and dragapult, knock out one shots dragapult unless bulky screen setter. also I've found, or at least thought I've found it to be a good lead vs alolan ninetails with knockoff. Almost every, if not every time, ninetails will screen turn 1 vs you, so you can heavily neuter screens. Scarf set is also a less common option over band and setup meowscarada, so it can catch some players off guard on some of their faster and scarfed mons.
Cresselia - Being the only setup sweeper on the team Cresselia is just a good good mid/late game setup sweeper, if tera poison with 1 calm mind set on King gambit switch on, can outpace king gambit with moon blast, or at least leave it low enough to be revenge killed by most the team. The team is somewhat built around allowing it to setup and sweep. Tera Poison, leftovers, and moonlight on the mon to allow it to use decent defensive typing with levitate and toxic immunity to allow it to sweep without worry of major chip.
