===Ritual/group magic===
Metal - it's called a jam session, and it's pretty easy to do. You just get a bunch of metalheads together and they go all out, and God knows what'll happen but it'll be awesome.

Disco - it's called a dance off, and it has a formal structure. Each participant must outmagic (and outdance) the last, and they get to use their normal effects, boosted by how many turns went before them. When someone fails to outperform the last person, the ritual fizzles, and you'll need a new dance off

Hippie - they've got a dozen of these, it involves circles and drums and singing. You know what hippie magic looks like. It's very powerful in a very straightforward way, but getting a bunch of hippies to try to do the same thing is like herding cats

The Man - their entire system of magic is a shared ritual in the first place
