New Moves: Slack Off, Land's Wrath, Headlong Rush, Earth Power, Stealth Rock, High Horsepower, Stomping Tantrum, Fissure, Thunder Wave, Scorching Sands, U-Turn
Removed Moves:
Justification: This gives mega hera a much more workable typing (hello bug / ground), with recovery it can bully pokemon like great tusk, samu-h, lando-t, valiant, kingambit, kartana, steelix-mega, tyranitar-mega, etc. With a more offensive movepool alongside utility you can easily see this being used on bulkier teams and more offensive ones especially with its high attack stat and surprising bulk with a built in 20% DR with 80/115/105
Name: Empoleon
Type: Water / Steel
Abilities: Torrent /
Anticipation
New Moves: Rapid Spin, Calm Mind, U-Turn, Dragon Tail, Taunt, Encore, Thunder Wave, Spikes
Removed Moves:
Justification: These changes should make empoleon a decent force to be wrecked with in OU. in OU with anticipation it can tank hits quite well from things like heatran, charizard y, diancie-m, kyurem, latios-m, iron crown, zapdos, etc. With calm mind you can serve as a potential win con, with rapid spin you can focus on removing your own hazards, with d tail you can distrurb the enemy especially with spikes, thunder wave, and encore to make pokemon take advantage easier esp with flip turn you can pivot into pokemon who can take advantage of such a pokemon.

Abilities: Route Closed / Ice Body / Moody, Refrigerate
New Moves: Liquidation, Wave Crash, Hydro Pump, Scald, Flip Turn, Surf, Whirlpool, Triple Dive, Caltrops, Close Combat, Calm Mind, Bulk Up, Parting Shot, U-Turn, Hyper Voice, Tri Attack, Iron Head, Flash Cannon, Heavy Slam, Aqua Jet
Removed Moves:
Justification: With a water ice typing, glalie poses a much bigger threat to teams, esp with a movepool consisting of hydro pump + freeze dry which is a very broken coverage that iron bundle had. With this it can threaten them quite well and with tools such as moody to make it be even stronger, ice body to nullify the ice weakness or use refrigerate to toss out dangerous tri attacks or double edge
Name: Zapdos Galar
Type: Fighting / Flying
Abilities: Long Reach / Reckless / Super Luck
New Moves: Dragon Dance, Roost, Headlong Rush, High Jump Kick, Triple Kick, Sucker Punch, Defog, Switcheroo,
Removed Moves:
Justification: This tries to fix some of its issues. With long reach static and helmet are no longer much of a worry of it. It can now throw of its moves without fear of being punished that badly by a defensive zapdos. Reckless boosts its damage output and with HJK you can crank some good numbers with zapdos galar cleaning late game or opening a hole in the enemy. With setup you can take advantage of dragon dance and use moves like t kick to break through stalemates alongside long reach through skarmory or to setup late game and use reckless to go ham. Roost can be helpful to offset the damage from recoil and maybe will see use on some choice sets as a last slot. Sucker Punch gives it some form of priority to protect itself with while switcheroo allows it to shut down a setup sweeper with a choice item

Removed Moves:
Justification: Aggron-m has a new steel / fighting variant and now uses it to pose a threat to teams, with its new ability in heavy metal it can now take hits better from mons like gholdengo, aegislash, pecharunt, pivot mons in with volt switch and take advantage of the setup it has in bulk up in addition to the utility of nuzzle, caltrops, and knock off in addition. Scrappy allows body press sets to drop mons like gholdengo, aegislash, pecharunt, etc.

Regenerator / Moody / Wind Power
New Moves:
All: Hurricane, Stealth Rock, Work Up, Swords Dance

Tailwind, Petroleum Blast, Power Gem,

Brave Bird, Close Combat, Encore, Haze,

Close Combat, Brave Bird, Encore, Ice Punch, Icy Wind,
Removed Moves:
Justification: These mons have since lost their shine either with changes to them (lando-i) or have been outclasses at some point thanks to changes ot them. These hope to make them on par with others like getting some nice options like lando-i getting no guard, hurricane, and can now have pretty reliable focus blasts and also have good rock coverage on the special side. Torn-i gets things like comp to help special sets punish defog while it can now use hurricane to spam opponents down wth aerodynamism and also get good physical movepool to abuse SD with. Thundy i gets quite a bit of utility with stuff like encore, stealth rock and also having a good physical move to back up its nice attack stat
