How does the mode work?
You can make Pokémon have any sorts of moves and abilities, even if they don’t legally learn the moves/have the abilities. It’s different from Pure Hackmons, because, well, it’s more balanced. Here’s the banlist:
Clause and Ban List: The banlist keeps the"Balanced" in Balanced Hackmons. Here's our interim banlist for the beta BH8 Ladder (this will eventually move to a BH8 Suspects and Bans Thread):
Pokemon Eternatus-Eternamax Shedinja Zacian-Crowned
Moves Chatter OHKO Moves Double Iron Bash Octolock Shell Smash
Abilities Wonder Guard Pure / Huge Power Parental Bond Protean / Libero Shadow Tag/Arena Trap Moody Water Bubble Innards Out Magnet Pull Stakeout Illusion Contrary Neutralizing Gas Gorilla Tactics
Clauses
ComaTalk Clause: Sleep Talk can't be run on a Pokemon with the Comatose ability
Endless Battle Clause: Forcing an endless battle is banned, similar to the rest of PS
Evasion Moves Clause: No moves that can increase Evasion are allowed. This does not include abilities or items that may modify Evasion passively such as Sand Veil or Brightpowder
Sleep Clause: Only one Pokemon on the opponent's team can be put to sleep at a time. This excludes self-inflicted sleep or Comatose
Forme Clause: You may only use one of each forme of a Pokemon on your team. (Example: you can use both Darmanitan-Zen and Darmanitan-Galar-Zen on the same team)

Hope this helps! :)
Balanced Hackmons is an Other Metagame where nearly anything is possible, up to in-game limitations. You can assign any moves and abilities to any Pokémon—even ones already in their Mega forme—and use unreleased moves, items, and Pokémon! When looking at the clauses below, you should note that the Species Clause is missing, meaning you can run those teams of six Mega Mewtwo that you always wanted to do!

Balanced Hackmons is essentially a mode with infinite possible combinations for any one Pokémon. You can give any Pokémon essentially any move or ability that is not banned. Example, you can have a Glaceon with Sturdy for example. Also, Pokémon can have 252 EV in EVERY stat. By all these factors, typing, items and base stat total all have a much greater importance that OU for example.
