Arena: High Temple of Enlightenment
Still yourself for a second. Meditate. Afetr that, destroy everything.
This is pretty much the destiny for battlers on the High Temple of Enlightenment. It sits atop a hill in a hihgly urbanized territory (although it's by and at large antique, at least in appearance), and within it, many study quietly or carry out rituals, all towards the goal of ultimate knowledge. The heightened flow of information in magical form affects those who battle in the designated arena that lies in its basement; the tendency is for them to suddenly become more knowledgeable while they fight. However, the ideas gained seem to go away as suddenly as they come, so, it's not considered a reliable form of enlightenment. Not by most of the students, anyhow.
Pokémon are affected by this as any student. As such, at the end of each round, they learn a given move -- any move, up to, including and specially legendary signature moves -- that they don't already know. They can only use it once, however. If a Pokémon has yet to use their learned move at the end of the round, they cannot learn a new one. An action can be spent to forcibly remove a learned move from the mind, and a failed attempt to use the move will not cause it to be forgotten (although it does peter away if the move is used successfully, but fails nonetheless).
It has not come to the awareness of the students yet, but, sleeping in the arena will cause the knowledge to flow in and out at a frantic pace. As such, any Pokémon put to sleep in this arena will not carry out any orders, and instead, will constantly fire off random moves, as though using Metronome over and over.
For purposes of convenience, even if the temple is destroyed -- even if the whole hill and the entire city are destroyed -- the effects of the arena will apply, and likewise if the Pokémon simply leave it (unless they are also leaving battle in the process).
