OP mostly taken from Gen 7 Mix and Mega thread
Rules:
Mix and Mega is an Ubers-based metagame that allows you to use any transformation item on any permitted pokémon. When that Pokémon then transforms, it undergoes the same stat modifications that the original user of that item does, along with its ability and any type changes that the altered form has compared to the base species. Primarily this takes the form of the Gen 6 Mega Evolution mechanic, with the usual restrictions of one per team removed, but also included are the Red and Blue Primal Orbs as well as the Gen 8 Rusted items.

FAQ:
Q: How many Pokémon may I mega evolve on a team?
A: You may Mega Evolve any number of Pokemon on the same team.
Q: How do Mega Stones that add types function on Pokémon that are given a secondary type equivalent to their primary type?
A: If you use a Mega Stone that gives you a secondary typing that's the same as your primary typing, you no longer have a secondary typing (ie: Altarianite Togekiss). In the case of Aggronite, any Pokémon using this stone will lose their secondary typing (ie: Aggronite Tyranitar)
Q: Why does my Darmanitan-Zen revert to its base form upon Mega Evolution?
A: Mega Evolutions cannot be based off of alternate in-game form changes, and hence they revert to their original forme.
Q: Can Knock Off, Trick, e.t.c. be used to remove a transformation item from its holder?
A: A Mega Stone cannot in any way removed from its holder if the holder can Mega Evolve with it, regardless of whether the holder is the "correct" species or not. The same goes for the Primal Orbs and Rusted Items.
Q: What happened to Aggronite?
A: Aggronite remains in the metagame but has updated mechanics that will now remove the secondary typing instead of adding Steel typing. However, Rusted Sword and Rusted Shield do add Steel typing to pokemon that hold them.
Q: What about native Mega Evolutions (like Tyranitar @ Tyranitarite)?
A: Native Mega Evolutions are only allowed if the Pokémon in question isn't restricted from Mega Evolving AND if the Mega Stone is allowed.
