Madness Type-Dark Effect: Drastically raises stats, but confuses the user. In-depth: distributes plus four to any of the pokemon's stats(even all to one,) but confuses the user for at least four turns.
I've never heard of Muse, but this is what I'd think of for a move called madness.
Muse is a British band that is sort of a modern incarnation of Queen. It has it's own style, but a lot of the things that make it good also make queen good. The lead has a wide vocal range, they play across a large variety of genres, and there is a guitar solo in pretty much every song. If you haven't heard of them, I'd suggest listening to their bigger hits like Madness, Uprising, Starlight (another great move name btw), and Supermassive Black Hole
I reccomend also Listning to Showbiz, Citizen Erased, Bliss, Plug In Baby, Dead Star, Butterflies & Hurricanes, Map Of The Problematique, Panic Station & Supremacy some of there better songs (in my opinion)
Starlight & Uprising are very good too though, Listen to a live version of Uprising though.
Just popped in to say that Muse is absolutely awesome (although I do tend to prefer their older stuff). Sunburn, Dark Shines and Micro Cuts all sound like good names. Also fond of Spiral Static as a sound-based attack.
